Mardili Puck Locks for Trailers,Hidden Shackle Padlocks for Trucks & Vans | 3 Pcs Heavy Duty Padlocks with Keyed Alike, 6 Keys Included, 2-7/8 Inch, Silver

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.

These did not work on my trailer, I have two trailer and it did not work on neither one. Had to destroy two locks because they got stuck. Not like major brand, pin steps up in shaft size, cannot insert fully, will not lock. Will not work like major brand. Bought 3 more locks from Harbor Freight $11.99 and they WORK.

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

These did not fit my trailers plus interstate cargo trailer. Great quality, look and feel otherwise

These locks are excellent. However, the trick to making them operate smoothly is to spray the insides with some lithium grease. Without the grease, they stick and are hard to open and close.

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.

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