Model 2178-U

Boat Trailer

I recently purchased Proven Lock 2178-U for my boat trailer. The lock is very well built giving me the peace of mind that my boat is protected. The construction of the lock is solid and the fact that I can lock the safety chains is a great feature. I would highly recommend this lock for anyone looking for trailer security/protection.

Boat/Cargo Trailer

I bought four of these locks. Three for my company's cargo trailers and one for my boat and I've been extremely impressed with them. This past weekend I was at Jackson Lake in Grand Teton National Park, and I couldn't help but notice that my boat was the only one on the dock secured with a truly heavy-duty, unbreakable lock. Almost every other boat had the typical cheap locks that could probably be defeated with a hammer or bolt cutters. The build quality on these locks is outstanding, and they give me real peace of mind knowing my trailers and boat are protected. They're definitely more expensive than the average lock, but you get what you pay for. If you're serious about protecting your equipment, I highly recommend them.

Peace of mind

I tried two other lock brands and they did not fit at all. I found the right lock for my trailer and hitch and customer service confirmed for me based on a picture I provided. Put it on my trailer the same day it arrived and I have peace of mind.
