Ratings & Reviews
Exactly as advertised. Excellent quality and fits my hitch like a glove.
I have been a repeat customer. They have stood behind the product and service has been great.
Perfect fit. The lock looks great and is a much needed accessory for RV's.
Quality product and fast shipping, will purchase again in the future.
Fits well over the trailer ball. Strong, well made.
Works great. I park my trailer in public areas on occasion. It hasn't gotten ripped off yet!
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.
Having one key to match 7 trailer locks is a great plus.
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.
Looks very sturdy. Fit my trailer coupler, which is 4 inches wide, where other locks would not fit.
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.
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.
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!
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'
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
Locks are good quality, I have several of them and am buying these additional two to replace the ones that I had to cut off due to misplaced keys. For what it's worth, they were not easy to cut which is a good for their purpose.
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.
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.
This works great and Etrailer was bale to get it keyed alike to my hitch locks also.
Wow amazing product and easy to install .More heavy than I thought.
The lock works great with my travel trailer. As always, etrailer shipped the item super fast! Thanks!
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.
Installed on trailer seems to work well
Just what I was looking for! Perfect fit on our 27 ft 2021 Jayco travel trailer with 4.5 inch wide coupler.
Awesome product.
