Just as described. Read the instructions before installing and there will be no issues.
As described, quality product, made in USA.
Everyone was very helpful with all my questions locks nice heavy duty.
great product very fast shipping
I bought these locks because they are all keyed alike. Works great.
Love the option of keying them alike, no more fumbling around with three key for three locks anymore!
Great product - had the smaller for my 1/2 ton truck but got the larger one. Great service from Etrailer - quick service
This product is perfect for my needs. The lock has a dust cover that keeps it clean no matter the conditions. Just a fantastic product and a very reasonable price that does what it claims!
Put two of these on my boat and ATV trailers. Work perfect. Fast shipping, too.
Great Product.... Great Service.... Fast Shipping and easy installation......etrailer is the best..... Thanks Madison P
quality product as always from etrailer. I really liked having locks keyed the same, tired of having to keep up with soo many keys.
The lock is really excellent quality. I use it to secure a kayak trailer. So it's really only exposed to summer type weather. The service from etrailer was quick and efficient.
I called to get keyed alike locks and got three different pinned locks that were supposed to be keyed alike
This coupler lock a quality product. Perfect for the application which I'm using it for, which is for locking the spare tire on the bracket fabricated.
Both stainless hitch and coupler locks were exactly as decribed and were delivered promptly. I use etrailer.com for all my towing related equipment.
Just what I needed. These guys have everything. Very quick shipping and arrived as stated. Their videos are great and helped me decide on which locks I needed.
Excellent quality - great customer service - got mine keyed with hitch receiver lock both by Deadbolt - great products and look great and are very secure locks!! Really happy with both!!!
Good little item, but stout. Keyed end is screwed on/off with key inserted. Remove the key, pop the cap on and it's ready to go. Will be used to secure bikes to Swagman hitch carrier for travel and/or storage. Swagman carrier is secured to an anchored stand for storage
In doing business with etrailer, it was a great and easy process.
All of the people I talked were more than helpful.
Their bosses should be very proud of their performance.
I bought 4 coupler locks to use on my trailers and one key fits them all.
Thank you so very much!
Love it. It fits in the safety pin hole on a 2” ball hitch. I also got mine keyed alike. That is a pretty good idea to offer as an option.
Product was as advertised, and company offered great customer service after a snafu with the Post Office. Will order again from them for our trailer needs.

Love the lock, easy to use and keeps the trailer secure....definitely recommend.
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 still working great and keyed alike has simplified my key rings. Highly recommend these
We are very pleased with the lock and especially with its companion hitch "stinger" lock that is identically keyed. Etrailer was very accommodating in working out the keying for this product. highly recommended!

We continue to give these locks a 5 Star rating!
It is listed as only working with 1/2" thick couplers. I had one years ago that would work on variable thicknesses, eneded up losing in when moving. Was unable to find one that would snug up tight (no gap) and made of SS. My current coupler measures 9/16" thick. I took a chance and ordered this one and was very happy that it works perfectly on my current 9/16" coupler. Snugging up tightly and key come out once tight. Can't say they all will but happy I took the chance and it did work!
The product is great, BUT it doesn't fit my Grand Design Imagine latch.
