Prompt service, easy and reliable tracking, and very fair pricing. All this combined with a huge selection makes it a very pleasant shopping experience



by:

It fit perfectly on my boat trailer act uator.



by:

Great Product! We ordered 6 of these for our fleet of trailers. Very convenient with all the same key. Also purchased the matching coupler locks.
We are very happy with both the products AND customer service at etrailer. They are our first and only call for trailer supplies.



by:

Perfect for the Demco EzLatch on my utility trailer. Very easy to use and provides the security for my trailer that I sought.

Works very well, and as intended. Adds a sense of real security & safety.



by:

Easy to use and fits my shorelander tra iler.



by:

I was sent a follow up email asking how I liked the lock, and I have to say that I liked it enough to buy it a second time after I LOST THE KEYS!!! Because losing keys in my job!!! But yes it is a great lock for my trailer, because it has an odd coupler that a pin goes completely through it and you can’t use a standard padlock or coupler lock. The coupler locks sold at local stores were not long enough to go through the coupler, so I has to search the internet and I found this at trailer.com and it works! I would definitely recommend this lock if you have this style of coupler.



by:

Great locks working well. Like the idea that they are keyed alike!



by:

Does the job but not sure it could hold up to a hammer.



by:

Good value since the coupler lock works exactly as intended. Best part - even tho outside year around in Seattle weather, no corrosion since chrome plating more than adequate. Works on both electric and surge brake couplers with thru-body locks requiring extra length (span).



by:

These seem to be made well. Yet to be seen how they hold up over time. Having several trailers, the keyed alike feature was important to me and I was able to order the lengths I needed for the various coupler types. I saw some reviews indicating that the operation of these was slow or tedious. I found that insert the key, hold the key and spin the black end was simple and quick.

These are working well about a year later. Happy with them



by:

I ordered this lock and an etrailer branded coupler lock as etrailer’s website says it can be keyed alike to any other etrailer branded lock. I required them to be keyed alike. I received two locks that were keyed differently. There were extra lock cores in the box like someone was going to change them out, but shipped them without doing so. I followed up with customer service to inquire as to why and was told that these locks can only be keyed alike to the same type of lock, not other locks. I was then told they would send the correct replacement lock. Then was told that was not possible. I requested to return my order for a refund as the website was very unclear as to what locks could be keyed alike. I received a refund for less than the cost of one of the locks. Worst experience with etrailer ever. I won’t be buying from them again.

Takes to long to un screw and come apart. Only used it a couple of times.

PURCHASED A TRAILER LOCK, IT FIT PERFECTLY. VERY HAPPY WITH THE PURCHASE

everything is still working great after a year of use.



by:

Does what it is supposed to. Not sure how easy it would be to snip or cut through, but I use it as a component of my security on a lightweight teardrop



by:

I received the coupler lock. My coworker joked "That will only stop a honest man" You could cur this off with a hack saw in thirty seconds.



by:

Thank You etrailer! Coupler lock would not work Called and explained that the lock would not open? I received on three days later and has worked fine since. Great service!!! My number 1 go too!!!



by:

As described, perfect fit and looks good. Quick ship as well. Thank you etrailer.com!!



by:

I drive in all sorts of weather, still looks and works like it did when it was new after 1 year.



by:

This steel lock mechanism will only keep an honest person away. I hit the lock with a hammer and it cracked off, rendering it useless. The key loxk has to be spun on, so if you keep the rubber protector in place its a pain to screw on with the key inserted. Get a reL trailer lock that goes in the ball mechanism. Do not wastevyoyr money on this styleock it is useless against and criminal intetent.

Any lock can be tampered with until it fails. Item # BLTL-50-40D would be a good option for you.



by:

Great product! I bought this coupler lock to replace others that kept bending while pulling my boat. After a year and fishing about once a week, pulling over mountains, and having to hit the brakes hard a couple of times, this coupler has held up superbly! etrailer is my go to place for all trailer products, great selection of products, super description of their products, often with video link, fantastic service and very competitive prices!

Super! Works as good today as the day I receivedit!



by:

Great product and I was able to get it to match the key on my other trailer lock



by:

I have broken 2 locking coupler locking pins due to tongue moving forward with surge brakes. This product is not an ideal solution as you need to spin on and off with the key to lock and unlock the pin. Turning a key 10-15 times to screw in and out is a pain. This will be a back up at best to some other solution I am still seeking.

You may like this product better as it is just one turn of a barrel key which makes it a little easier: Item # MT76FR.

Fits great



by:

I was needing a pin lock designed like there is nothing was hanging down to catch my hitch. Works perfect.

This is my second set (the first set is still working and on a different truck)

  • Recommended Coupler Lock For Surge Brake Actuator On Continental Boat Trailer
    I may have another option for you, but the EZ Lock Trailer Coupler Lock # BLTL-20 you were looking at is only confirmed to fit the Bulldog Collar-Lok Couplers so it will likely not work on your surge brake actuator. I looked up your Continental Model A2485B-8500 trailer and to lock the surge brake actuator you will need the etrailer Surge Brake Coupler Lock # e98888. I included a video of the # e98888 for you to take a look at.

  • Is There A Coupler Lock Compatible With The Demco Hydraulic Brake Actuator DM72VR?
    To lock the latch of the Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs # DM72VR you were looking at you will need the etrailer Surge Brake Coupler Lock - 3-3/8" Span - 1/4" Diameter - Chrome # e98888. This lock goes in the hole shown in the included picture and keeps the coupler closed so no one can hook up a hitch ball when the trailer is sitting around, and will also make it so no one can remove the trailer from your hitch ball when it is hooked up to your truck.

  • Distance Between Bolt Holes of Demco Channel Tongue Coupler DM16080-52
    Thanks for the photo, and the distance between the front and rear bolt holes is 5 inches for the Demco Channel Tongue Trailer Coupler - Silver - 2-5/16" Ball - 3" Channel - Bolt On - 21K # DM16080-52. So if you measure the bolt holes on your trailer's tongue and they are 5 inches, this coupler will bolt right into the holes you have. I do recommend adding a coupler lock for added protection, the etrailer Surge Brake Coupler Lock - 3-3/8" Span # e98888. I have added some links below...

  • Can the MaxxTow Coupler Latch Lock Be Keyed Alike
    Since the MaxxTow Coupler Latch Lock for Surge Brake Actuators # MT76FR can not be keyed alike, what you're trying to do won't work, you'd get two different keys. However, the etrailer Surge Brake Coupler Lock # e98888 which has the same span and diameter as # MT76FR, can be keyed alike. To order these keyed alike, you'd need to just select the "keyed alike" option and you'll be all set.

  • Coupler Locks For Dexter A-60 Brake Actuator When Towing and When In Storage
    We do have locks that will work with your Dexter A-60 Brake Actuator # DX56FR. The Coupler Lock # e98888 will allow you to secure the trailer to your vehicle when towing. This lock pin replaces the included push pin which comes with the actuator. For storage you will want to use the Fastway Universal Trailer Coupler Lock # FA86-0015-316. This can be used with the coupler lock above as well.

  • Recommended Hitch Pin Compatible with Trailer Hitch Receiver Mounted Forged Tow Eye # TR63045
    The Trailer Hitch Receiver Mounted Forged Tow Eye, # TR63045, will accept a hitch pin that is 5/8 inch diameter and at least 2 inches long. The Pin and Clip, # PC3, that you have referenced will fit. I recommend a locking hitch pin, like the Trailer Hitch Receiver Lock - Flush Design, # e98888, to deter theft. I have included a video review that features this lock below.

  • Can Hub and Drums On 1990 Four Winns Boat Trailer Be Reused When Replacing Brakes?
    You do not necessarily need to replace the hub and drum assemblies on your 1990 Four Winns Tandem Axle Boat Trailer as long as they are still in good shape. The only way to tell will be removing them and checking the inside where the brake pads and magnets contact the drum for any uneven wear. While the drum is off you will want to measure the depth of the drum as shown in the included diagram, as the # AKFBBRK-35-D you were looking at are only 2-1/4" deep. If you find that you do need...

  • Locking Options for Brake Actuator
    You can use the Trailer Coupler Lock for Surge Brake with 3-3/8" Span, part # e98888, to lock a actuator like # T43397007K once it's attached to the hitch ball through the latching mechanism on the top of your coupler. This product has a wide width so it will clear the sides. The Master Lock 1-7/8" and 2" Trailer Coupler Lock, part # 377DAT, is an option that locks the trailer when it's not connected to the hitch ball. It attaches where the trailer hitch ball would go.

    For your Demco Channel Tongue Trailer Coupler part # DM13203-52 I recommend using the etrailer Surge Brake Coupler Lock part # e98888. This is designed to place through the coupler pin hole just under the latch and keep it from being able to operate. This will prevent it from opening or closing eliminating any issues. If you want complete coupler coverage the etrailer Trailer Coupler Lock for Flat Lip 2-5/16" Ball Coupler part # e98895 is an excellent choice. They are both very easy...

    For your Bulldog coupler you would have to use the Trailer Coupler Lock, part # 28012. This is a coupler lock with an inside width of 3-3/8 inches. I pulled the Bulldog coupler from our warehouse and measured the size of the lock pin that goes in the coupler. It measured 5/16 inch diameter and a length of 2-3/4 inches. I tried the lock in the coupler and it fit and did keep the collar lock from opening. See the picture to the right that will show it installed on a similar coupler.

The # e98888 is not only the right size but also has a pick-proof lock mechanism as well as a really handy rubbered end which makes it much easier to grip for when you take it on and off.

    It sounds like you have a Collar-Lok coupler such as # BD028244. For that type of coupler you could use lock # BLTL-23. The body is aluminum but the pin inside that goes way up into the coupler is steel. It fits 2-5/16 inch Collar-Lok couplers. For 2 inch models use # BLTL-22. Another option, if your coupler has the pin behind the collar to keep the collar from sliding back, is to use a lock such as # e98888 in place of the pin. This would prevent the collar from opening all the way. Or,...

The most likely replacement option is the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # DM13205-95 which is for trailer frames that have the standard 50 degree frame and requires a 2-5/16" hitch ball.
