by:

These trailer coupler locks are great, easy to install and easy to take off. More than pleased the product and the shipping! Thanks guys, keep up the good work!



by:

Works great. I park my trailer in public areas on occasion. It hasn't gotten ripped off yet!



by:

Seems sturdy. Unfortunately Fastway is one of those companies that thinks it is necessary to collect marketing information for you to complete warranty registration. Minus 1 star for that.



by:

Ball not as big as it should be and had to shim it. Tricky to get it tight enough to stay on my trailer hitch. Very heavy duty and seems to do the job.



by:

High quality product. Lock bolt is stro ng.



by:

I was able to break this off my hitch with a hammer because the key hole kept freezing up. Your product almost made me late to an event. So I ordered a replacement to see how this one works out. This order too way longer than expected to be delivered. I doubt I will be ordering again.

That is one rough way to break the lock off. If the lock is freezing up on you we recommend using a silicone-based lubricant spray like part # RM-747 to help loosen things up. Stay away from using WD-40 and it will muck up the lock internally. If the spray does not work be itself then what you can do is use the spray, then the key and lightly tap the back of the key to make sure it is fully seated in the lock before turning.



by:

I have been a repeat customer. They have stood behind the product and service has been great.



by:

It's a great product it does everything that is supposed to do highly recommend getting it



by:

I have a 2" collar style coupler. It fits, but not as rock solid as I had hoped. I found that reversing the lock (with the keyway facing the tongue) worked best, but that makes it a bit fiddly to get the key in the lock.



by:

easy peezy transaction . no headaches at all !!!!!



by:

Works great, no problems with functionality. However I use this on a trailer on the Gulf coast, and the finish is already shot with rust. Would not recommend this finish in this environment.



by:

I liked how you shipped my product asap and got to me fast. Thank you



by:

Having one key to match 7 trailer locks is a great plus.



by:

Perfect fit. The lock looks great and is a much needed accessory for RV's.



by:

Wow amazing product and easy to install .More heavy than I thought.



by:

This works great and Etrailer was bale to get it keyed alike to my hitch locks also.



by:

The product showed up on time the quality looks real good just installed them on my 5 x 8 utility trailer and my RV trailer so far so good thank you for the fast shipment and the tracking system you have works out real nice have a great day



by:

Delivered early and great product that fits. Thank you



by:

the product is of excellent quality and beefier than other products.been my first order from you my only issue was following the tracking . It was stuck in Michigan for a week on line and I was notified by my gf that the package was delivered after I had just looked and it was still in Michigan according to the order number. You have an excellent website Best I've seen by far anyplace. Awesome videos to help . Thanks to all at Etrailer.



by:

This is exactly what we needed... Our "OTHER" hitch lock was overpowered in a matter of a minute, we stepped up our game with the combination of this Power house of a securement system AND a 'DENVER BOOT'



by:

Good Lock.



by:

Got this coupler lock to fit securely on my trailer. For the most part, this lock appears robust. This with a good cable lock through the wheel should be an effective theft deterrence.



by:

Looks very sturdy. Fit my trailer coupler, which is 4 inches wide, where other locks would not fit.



by:

I found what I needed quickly. I paid for three day shipping and it got here early! It turned out to be perfect. The boat we were selling sold to the first person interested, which would have been after the lock arrived. Very pleased.



by:

This thing is BEEFY!!!!! This will work great, wish I had known about this product years ago!!!

    I have a solution for you but the Blue Ox Trailer Coupler Lock item # BX88351 is not capable of being keyed alike. Instead you will want the Fastway Universal Coupler Lock item # FA86-0015-316. This coupler has the same abilities and functions. It fits most 1-7/8", 2" and 2-5/16" ball couplers. You will want to order as many of these couplers as you need and they will all be able to secure with the same key.

  • Recommended Coupler Lock for Trailer with 2 Coupler
    The Fastway Universal Trailer Coupler Lock part # FA86-0015-316 is my recommendation for a trailer coupler lock that will be used to protect the trailer while not in use and detached from the tow vehicle. This coupler lock is universal so it will work with pretty much any trailer. The anti-drill pin helps further prevent the lock core from being drilling and the hardened shackles help further prevent the chance of it being able to be cut.

  • Wheel Lock And Coupler Lock Recommendation For Trailer To Deter Thieves
    The best wheel lock system we offer is the Lock'em Magnum Wheel Lock, part # RA-25. This system will work on 12 to 17 inch wheels. One side works on 12-15 inch wheels and the other side works on 15-17 inch wheels. The arms measure 1 inch X 7/8 inch at the narrowest point and would be extremely difficult to cut off with a bolt cutter. For added security, you may want to check out part # FA86-0015-316.

  • Recommended Trailer Coupler Lock for Pole Tongue Trailer
    I'd recommend a universal coupler lock set like the # FA86-0015-316 from Fastway. The coupler lock is compatible with 1-7/8, 2 or 2-5/16 inch couplers. I'd also go with a latch lock like # e98887 to prevent the coupler from coming unlatched while towing. It'll also prevent the trailer from being hitched up.

  • Coupler Lock Comparison for Securing a Travel Trailer
    Any type of lock you put on your trailer will be a theft deterrent.

The Diversi-Tech lock will be harder and noisier to break off than the Master Lock coupler lock which is a better deterrent for thieves. Wheel locks are also a secure option, but can be tedious to apply and still gives thieves a chance to...

  • How Theft-Proof is the etraiiler.com Coupler Lock # e98888
    Locks are for keeping honest folks honest, just about any lock can eventually be defeated if the crook is determined enough. The lock you mention, part # e98888, provides what I would call minimal deterrence against theft. If there are two identical boat trailers parked side by side, one using the # e98888 lock, and the other unlocked, the lock will do its job and deter the crook from taking your trailer. One quick snip with some bolt cutters, and the lock will be defeated, but the thief...
