Product Description
The Master Lock No. 5 is the 2" laminated steel padlock you see on job-site gang boxes, utility gates, fence chains and lockout boards. The 5KA A112 is that lock keyed alike to Master key number A112: every 5KA A112 opens with the same key. Buy as many as you need and one key runs all of them, today or next year.
The body is layers of steel plate riveted together. The shackle is 3/8" hardened boron alloy for cut resistance. The cylinder is a 4-pin tumbler and it is not rekeyable. If you need a different key later, you buy a lock on a different key number. You cannot re-pin this one.
Pro-Tip: The key number is the whole point of a keyed-alike order. When you add locks to an existing set, read the number stamped on the key or on the lock, then order that exact A-number. A 5KA on a different number will not match your keys.
