Mindy 70mm Heavy Duty Lock Warehouse Waterproof Keyed Padlock High Security Padlock with 4 Keys

It's a big and heavy lock but internal mechanism is not up to the standard

First time it was unlocked, it came apart in my hand.

Using to secure our five-bar gate access to the drive. Very solid lock with easy mechanism. A bit fiddly to lock to begin with as the key needs to be perfectly horizontal for the lock to work, but simple once you get used to it.

A good size and strong padlock, unfortunately it has rusted very quickly and is problematic to open, we're constantly having to use wd40 and other things to keep it working.

brilliant little lock , stainless steel , another good fact is that you cannot leave lock open without the key being inserted
