Mardili Hidden Shackle Trailer Puck Padlocks with Keyed Alike, 2-7/8" Puck Lock,Moving Trucks & Vans Door Lock, Soild Steel, Pack of 3

these locks are perfect, for my trailer, you can't cut through this lock so easy, you going to need a torch to get through this lock, i can sleep easy at night.

So far so good. Heavy duty locks that should be difficult to defeat! My only issue is that after sitting through a couple rain storms one of the 3 locks I have on my trailer showed some rusting of the lock mechanism and was a little sticky. I hit all the locks with some WD-40 and all is well, but makes me wonder a little about the long term. These aren’t locks that would be easy to get off if they were to quit working.

I verified the measurements according to their product listing, but upon receiving it, I found that it didn't fit a standard trailer door latch. The actual measurements were about 4mm or 1/8" smaller. The lock's depth was insufficient to engage through the latch hole, and even when it did, it took me a frustrating 20 minutes to unlock it due to binding issues.

Just a little sticky when wet as moisture created rust within a few weeks. WD 40 helped. Locks look great on trailer.

Works as advertised and seems to be great value as these were the cheapest I could find

Locks fit the function is great to the application, security is top of the line. easy to open and shut!

These seem solid enough, however, at 5/8" the slot is too narrow to actually fit over the trailer door clasp. I ended up returning to get something 3/4" wide. Makes all the difference.

Very well made product. Fixing to place another order soon.
