Rock solid hockey puck lock that protects my shed out back. With a hasp that has hidden screws, this lock does the trick. Hasp is something you have to buy separate at the hardware store and know what you are getting.

Rear opening dimensions are approx 1 3/4" by 3/4" as you can see by the tape measure.

I added the 2 photos for the purpose of answering a question for someone on the size of the lock body opening. The lock looks "pitted" but allow me to clarify what that is. I have placed a good amount of motor oil on the lock (and in the lock mechanism to make sure it will not freeze in the winter). The lock protects a "cabinet" or "hutch" that must be outside year round in Connecticut. Therefore what you see is a mixture of the coating of oil which I applied on purpose and some dirt and dust. Not a defect in materials.

I bought two of these locks to use on the back of my enclosed motorcycle trailer. I wanted something that would be secure, not bounce around and look good too. These locks fit the bill. When I first searched the web I went to the Trimax home page. Then I searched Amazon, and once again they came through, got them for 50% less! The two locks are keyed alike and each came with 3 keys, so basically I have 5 spares. I added a tiny bit of lubricant (Ballisol) to the shackle area, both inside and out since they will be exposed to the weather all the time. They are easy to operate and are heavy duty locks.

I highly recommend this lock if you have a standard trailer locking bar with the two piece (one swings into place) hasp mechanism. It would take a expert lock picker to get these off, because there is no place to pry or cut them off.

Great product, great price, Amazon rules.

look great work great. had one before and it rusted in the keyhole which made it hard to use but never made it impossible. I wont be suprised if it happens again but still worth it. So theres your warning for possible rust down the road. Takes a long time though.

Nice lock. Very substantial. I had a shed built and didn't like the cheap little hasp that took a normal padlock. The thought of securing thousands of dollars in lawn equipment with a $5 hasp and padlock didn't seem like a good idea. This, combined with the appropriate hasp installed with carriage bolts keeps me pretty at ease.

These trailer lock work AWESOME!!! My brother is the one who brought me to these, because they can not be cut like normal locks. I was going to order the 3 identical keyed but was significantly more expensive so I ordered the individual locks and got them keyed ALL the same anyway.

As another reviewer has pointed out, this lock is susceptible to rust -- to the point where I had to use a hammer and punch to free the internal mechanism. On another occasion during the winter I had to use a propane torch to get it to open -- maybe rust, or maybe water freezing the internals. In any case, not very helpful if you're planning to use it on a trailer.

Best to look elsewhere.

Bought these to put on my motorcycle trailer so I would have the peace of mind that everything was protected. Theives are more likely to rip the doors off than to try to break these locks. They are solid and fit beautifully on my Haulmark trailer. I just hope they hold up. Will update after the winter in UT.

Well, lets see, I received this lock in a package all the way from where ever, I'm amazed just with that, so, I open the package take the lock out and put it on my trailer and guess what! It locked my trailer door and it doesn't come off unless I unlock it, I'm impressed and very happy with the performance of this lock! Thanks Trimax!!
