Product Description
A5100 American Lock 1-1/2" Solid Steel Rekeyable Padlock, 1" Boron Shackle
The A5100 is the American Lock solid steel padlock that facilities departments standardize on. The body is case hardened and chrome plated, and the shackle is boron alloy, which resists cutting better than ordinary hardened steel. It is rekeyable and takes the 5-pin APTC12 cylinder, so it can join a keyed-alike or master keyed system.
This is the 1-1/2" wide body with a 1" tall shackle. The 1/4" shackle suits hasps and small staples where a heavier shackle will not pass.

Q: Can I get it keyed alike from the factory?
A: Factory keyed alike and master keyed versions carry different part numbers (KA / MK). This listing is the standard keyed-different lock.
