Video Transcript for Curt 2 inch and 2-1/2 inch Hitch Lock Review

Today we're going to be taking a look at Curt's hitch lock for two-inch and two and a half-inch hitches. This hitch pin's going to be great for protecting your accessories. Most accessories don't come with locking pins and many don't even come with a pin at all. Well this way you can ensure that your gears going to stay safe and protected attached to your vehicle.The hitch pin attaches to the barrel style lock. It's a nice thick stainless steel, so it's going to be heavy duty and durable. Anybody that tries to take this off, is going to be spending way too much time out here that they're going to draw away too much attention and they're just going to hit the road.

On the end of the lock you have a watertight dust cap. This is going to keep out any moisture, dirt, and debris, ensuring a long lasting smooth operation of your lock.Once you insert your key, you can turn the key to unlock the barrel and it comes off. You'll see here on the inside that it has a rubber gasket that keeps any moisture, dirt and debris out of the inside of the tumbler as well, making it nice and smooth when putting it back on.With this particular style lock, you do have to unlock it first, then slide it on and then you can lock it again with the key. The hitch pin has a three and five-eighths inch span, which is going to be great for two and two and a half-inch hitches. This also includes your class three, four and class five hitches.When you're ready to install it, simply take the pin side, slide it through your hitch and whatever accessory you have in it.

Then you'll want to unlock the tumbler, slide it on and lock it down. You can finish by closing your dust cap.It's not only great for your accessories such as your cargo carriers and bike racks, but also for your ball mounts so you can keep those safe as well as your trailer that's attached to it.The pin comes with two keys for convenience. This way you can keep one with you and keep one at home for safekeeping. Many customers on our website compared Curt's hitch pin to Tow Ready's hitch pin and they both are three and a half-inch span hitch pins and they're both going to do pretty much the same job.One of the biggest differences though is that our Curt here is going to be stainless steel, so it's going to withstand the elements much better than just the chrome plated finish that the Tow Ready has.And that completes our look at Curt's hitch lock for two inch and two and a half-inch hitches.

Can’t speak for durability yet since I just received it but seems to be a quality product which I expect it to be. Fits perfect on a 2011 GMC 2500HD receiver hitch.

Still works great no problems at all.



by:

Could not get the hitch lock off. Had to use a crow bar & hammer. Then had to use a dremmel tool to modify stem at locking mechanism.



by:

Overall I am very pleased with my ETrailer experience. Everything was pretty straightforward and my products came within a reasonable timeframe. My only suggestion to ETrailer is maybe to package the expensive products in a outer box. The product that I ordered was on the pricy side of things and I came home to see my expensive product sitting infront of my driveway, open to anyone driving past it. A criminal or an opportunistic person who understood the value of that product would definitely pose a concern. Other than that, this is a fabulous online store.



by:

Does the job but the mechanism doesn’t feel that solid and it’s a little difficult to lock and unlick



by:

Very easy to use and the rubber cover most definitely keeps the moisture out of the locking mechanism.



by:

Best way to protect your hitch from the ft.



by:

Quality product.



by:

Product arrived quickly and works as advertised. Fits loosely for Ford F250 Receiver.



by:

The product did not fit the hitch it was recommended for. It only fit the receiver part and not where ball mounts to hitch.



by:

Extremely fast shipping and a real quality product.



by:

It's a great lock that seats perfectly.



by:

High quality product and works effortlessly. The stainless steel lock looks great attached to my trailer cover too!



by:

Always I am having a great experience. Never had a problem in any order in all these years. Super fast delivery, perfectly packaged and great communication. Thanks



by:

everything went together just like stat ed.



by:

Glad it is stainless steel. Easy to use and fits well in the hitch. Nice product.



by:

Very helpful customer service. Asked advice from the expert which was very helpful



by:

Do not purchase this product. I ordered it and it lasted maybe 4 months. I went to remove it to switch it out and it was corroded and wouldn’t unlock and beat it off with a hammer. Then I called etrailer to ask about a warranty or replacement and they informed me that they don’t have a warranty on this.

The key to prevent corrosion with aftermarket products are to lubricate them often and remove them when not in use. Here are some more tips about prevention:

The SAFETY of my trailer and boat are ONLY trusted to e-trailer.



by:

Just received / installed the lockable hitch pin... just what I expected... exactly as described. Happy so far with my purchase. If it stands up to our NE Pennsylvania Winter weather with the snow and salt used on the roads without rusting, I'll be absolutely thrilled!

Some rust and corrosion inside and out, difficulty unlocking it so I cleaned it and loaded it with lithium grease inside hoping to combat the moisture that gets in and causes the corrosion



by:

Seems good so far. Plenty of length and no rust yet. I would like to see Curt Mfg list a load or class limit somewhere. The reason I bought this one instead of the ones at Tractor Supply, Lowes, Northern Tool, etc... is that those all had a 10000 lb limit on the packaging. This has none. No posted limit means unlimited?

Hi John, according to our tech experts at Curt, this lock is rated for 20,000 lbs.



by:

Love my new hitch for my 2019 Toyota Rav Adventure. At first, I didn’t think it would slide between bumper and exhaust system, but it did. My wife helped hold one side while a car jack was used to lift hitch into position. I used a rubber mallet to get into position to install bolts. About a half hour later, hitch installed! Only concern was when delivered, the box was split open and the hitch was sliding out. Thankfully, no damage, bump step and locking pin were still inside box and hitch bolts were taped inside receiver, otherwise they would have been long gone!



by:

Very well made, easy to install and quick delivery. Would not hesitate to use any of your products as needed.



by:

Had 3 items shipped to a fishery I was staying at on the Oregon coast. A bike rack, a bumper mount and a locking pin. The rack and the mount showed up as scheduled but the pin was lost in shipping. As it turns out the pin was not compatible with the Pro bike rack which I was told it was. I'm glad the other two pieces arrived and work fine and the pin is what got lost. etrailer is to refund the pin price and were very friendly about it.



by:

Sweet nice lock



by:

The product is just as described, but more importantly the customer service is outstanding. In an age where you can find the same products across multiple websites, etrailer stands above all with their great customer service. Follow through and helpful information makes etrailer a great resource not just another online vendor. For this reason I don't waste time web surfing and instead go right to etrailer every time.

  • Lightweight Trailer Towing Setup For 2020 BMW X5
    To tow a light weight trailer with the 2020 BM X5, you need a hitch, hitch lock, trailer wiring, and ball mount with ball. For the hitch, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76288 which is a custom fit hitch for your BMW so there is not any drilling required for installation. This is the only hitch option for the BMW at this time but Draw-Tite is a great brand that is known to make quality hitches. I have attached the installation instructions for your reference....

  • How To Select The Correct Hitch Receiver Adapter
    I contacted Thule and they informed me that # 515-0109 is not a part number nor could they tell me which bike rack that number corresponds to. If you could send me a picture of your bike rack, I may be able to offer an exact recommendation. In order to use a 2" shank on a Class I/II 1-1/4" trailer hitch receiver, you will want to use the Hitch Adapter 1-1/4" to 2" Trailer Hitch Receiver part # HTAD. To lock the receiver to the hitch, you will also need to use the Trailer Hitch Receiver...

  • Is The Curt Trailer Hitch Receiver Lock # C23519 Compatible With a Ball Mount For Towing a Trailer?
    Yes, the Curt Trailer Hitch Receiver Lock # C23519 is rated for use when towing. It can also be used with hitch mounted accessories.
    view full answer...
  • Does Locking Hitch Pin part # C23519 have a Weight Capacity
    Hitch pins don't have weight capacities because they don't actually bear any of the trailer weight. The downward force of the tongue weight of the trailer is so great that the ball mount is pinned into the hitch so hard that none of the weight is put on the hitch pin.

  • Do I Need to Modify the Curt # C96CR to Fit a Hitch Pin for My 2022 Chevy Silverado 2500?
    No, you will not need to do any modifications to the Curt Hitch - 2-1/2" # C96CR in order to fit a hitch pin. Since the C96CR does not come with a pin, it is always a good idea to have a locking hitch pin for extra theft-deterrence if you are planning to attach a trailer or accessory. For the pin, I recommend the Trailer Hitch Receiver Lock # C23519.

  • Stainless Steel Hitch Pin for a 2011 Chevrolet Silverado 3500 HD with Extra Wide 2-1/2" Receiver
    For a stainless steel locking hitch pin that is compatible with the 2-1/2" hitch receiver on your 2011 Chevrolet Silverado 3500 HD we have the Curt # C23519. This includes 2 keys, is 5/8" in diameter, and has a usable pin length of 3-5/8" so it can accommodate the extra wide receiver that you have. I have attached a review video for you to check out as well.

  • Availability Of Replacement Keys For A Curt Hitch Lock
    Hello Mark. The only way to get replacement keys for a Curt 23518 hitch lock is if you happen to know they key number. The problem with this is the key number is printed on the key itself, so unless you happen to have the key number written down somewhere, you are out of luck. The only option would be to find a way to forcibly remove the lock. Either cut it off with a grinder or drill out the lock core until it comes off. Then you will need to replace it with a new one. We do not carry...

  • Corrosion Resistant 2 Inch Hitch Ball and Lock for Curt Aluminum Ball Mount With 2 Inch Drop
    There are a couple of really good options for a 2" hitch ball and hitch lock to resist corrosion with the 8,000 lb capacity Andersen Alumistinger Ball Mount for 2" Hitch - 1" Rise, 2" Drop # AM3503. For a hitch ball you can't go wrong with stainless steel to resist corrosion so the best option is the stainless 2" Hitch Ball # SC23-C. Then for a stainless steel hitch lock I recommend the Curt Trailer Hitch Receiver Lock # C23519. I have added links to video reviews for you to check out...

  • What Size Hitch to Install on 2014 Subaru Forester to Allow Installation of Hitch-Mounted Twiststep
    Your 2014 Subaru Forester can be fitted with two types of hitch, either a 1-1/4-inch Class II type or a 2-inch Class III. Many hitch-mount accessory items like your Twiststep (and many bike racks, for example) have the flexibility to be used with either size hitch receiver. Generally a 2-inch hitch has broader compatibility with a range of accessory items. Often a Class III hitch will have a higher tongue weight capacity than a Class II hitch. If you have any expectations for using the...

  • What is the Weight Capacity of the Draw-Tite 5/8 Inch Hitch Pin PC3
    The class III and greater hitch pins like part # PC3 are never going to be the weak point in a towing setup therefore they do not have a working load limit (WLL) or break strength rating. This is pretty standard across all trailer hitch pin manufacturers. The trailer hitch and or ball mount will fail much sooner than the hitch pin will. I know it may seem crazy but I have never seen a hitch pin given any sort of weight rating before. If you really must have a weight capacity rating, then...

  • Steel Hitch Pin for 2-1/2 Inch Receiver and Steel Hitch Reducer
    There are steel hitch pins for your 2-1/2 inch trailer hitch but all of them have a zinc coating, such as the Gen-Y Hitch Pin and Clip for 2-1/2" and 3" Hitches - 5/8" Diameter x 4" Long # 325-GH-099; as you mentioned, for a stainless steel pin you would need a lock, the Curt Hitch Lock - 2" and 2-1/2" Hitches - Stainless Steel # C23519. If you didn't want a lock because you didn't want to keep track of another key, there is the option of BOLT locks, which are made of stainless steel,...

  • Difference In Pintle and Regular Mount, and Availablity of Pintle Mount For 2011 Ford F-350
    A pintle hitch ball is designed to be used with trailers that use Lunette Rings, a regular or conventional hitch ball is designed to be used with trailers that have couplers. You would typically find trailers with Lunette Rings on industrial or construction type trailers. For a pintle towing setup, you will need a pintle draw bar, pintle ball, pin and clip, wiring, and brake controller. For a draw bar, I would recommend Titan Forged Pintle Hook Mounting Plate, part # RP45294, which will...

  • Does Curt Hitch Lock # C23519 Work on Class V Hitches

  • Recommendation For Tough Hitch Lock That Has 5/8 Inch Diameter And Fits 2-1/2 Inch Receiver Tubes
    Hitch pins and hitch pin locks like the Curt Hitch Lock, Item # C23519, do not carry any weight so they do not have weight capacities. The weight is seated in the hitch, not the hitch pin, by the downward force of the tongue weight so something like the Curt Hitch Lock which has a 5/8 inch diameter and fits 2-1/2 inch receiver tubes will work well for you and your needs. I have attached a video for you to check out.

  • Does Curt SecureLatch Pintle Hook & Ball CU57FR Have Tongue Weight Capacity
    Good question, and there is not a tongue weight rating for the Curt SecureLatch Pintle Hook with 2-5/16" Ball - 2" Hitches - 14,000 lbs # CU57FR. This does not come with a pin and clip or lock, so I do recommend adding a lock to help protect your investment, the Curt Trailer Hitch Receiver Lock # C23519.

  • Are Any Additional Products Needed to Install Curt Trailer Hitch # 13354 on 2008 Acura MDX
    The Curt Trailer Hitch # 13354 that you referenced comes with all the necessary hardware to install on your 2008 Acura MDX, so you will not need any additional accessories to complete the installation. A hitch lock is not a necessity for the hitch installation; however, I highly recommend using a lock with both your bikes and bike rack. The Trailer Hitch Receiver Lock # C23519 is an economical way to safeguard your investment. Another option is the Hollywood Racks # HRLHPC2 which is a...

  • Can a Trailer Become Unhitched While Driving
    When towing a trailer there are several mechanical connection points: where the ball mount such as # C45010 meets the hitch receiver and locks with a padlock like # C23519; and where the trailer coupler joins the hitch ball. Some trailers may require safety chains as a safety measure or if the trailer has brakes there will be a breakaway kit on the trailer to engage the trailer brakes automatically in the event of the trailer becoming uncoupled from the hitch ball. An example of a breakaway...

This will be more than capable of towing your boat and trailer. If you don't already have the wiring, I recommend the Curt # C56161. This harness plugs into your Honda Odyssey's electrical junction box, which is located in your rear cargo area, beneath the trim panel on the passenger's side. Then...

  • Hitch Lock Recommendation for Rapid Hitch Adjustable, Aluminum Ball Mount Kit # AM3410
    The Rapid Hitch Adjustable, Aluminum Ball Mount Kit # AM3410 has a non-threaded hitch pin so a standard locking hitch pin like the part # C23519 could work. The Andersen locks part # AM3492 include a lock for the ball mount platform and the shank of the ball mount so this is a great solution as well.

  • Would the Trailer Hitch Receiver Lock # C23519 fit a Class V Hitch
    Hitch pins like the Curt Reciever Lock part # C23519 that you referenced do not have weight ratings because they do not actually bear any weight, the key is to find one that is long enough for the hitch on your vehicle. The # C23519 has been confirmed to fit the dimensions of Class III, IV and V hitches so it should work well for you. I attached a review video for you to check out also.

  • Reveiver Locks that are Keyed Alike
    This particular lock, part # C23519 is not available to be keyed alike. If you wish to have several keyed alike, your best bet would be to go with a flush design receiver lock like part # e98880. On the product description screen, there is a drop down menu for ordering multiple locks that are keyed alike.
