Master Lock (4) Keyed Alike Padlocks w/Thermoplastic Coating - 311KA-4

Great quality product

Dimension listed for B, inside height of shackle is 3/4 of an inch. Product that arrived is 2 inches, way too long for the application and is useless. Will be returning.

Overall, these are excellent quality heavy duty Master brand locks. 3 of the four are flawless. 1 of the 4 the lack cover came off (didn’t stay on tight) during the winter. It got a litter corrosion in the lock mechaninsim, which really surprised me as it was after only a few weeks use outside on our snowmobile trailer door locks. As a result, the key for that one is tricky as it doesn't;t insert and turn smooth. If these had been used for years and this happened, i wouldn’t think too much of it. However, it happened after its first couple of weeks of use. Otherwise, the other 3 locks and their covers work perfectly. No problems and issue with them, so given the affordable price for 4 of them, I still feel good about the purchase. All in all, these are very heavy duty key style locks and I would absolutely buy them again for future uses.

The picture is misleading. The coating on the shackle is very thick, so the inner diameter of the locks is only about 0.5 inch. The picture implies otherwise. Other than that seems OK. will comment later on how well they take weathering.

Description says if you order more than one box, all locks will be keyed alike. They are not.

Locks are great but perform poorly in winter as the internals like to freeze up due to the keyhole cover collecting moisture then freezing so you cant even insert key , once it was removed it did not freeze as often.

Pictures and dimensions suggested the next size up, which I would have preferred. These are OK, but not what I expected.

Appear to be good quality upon initial receipt.
