Rekeyable Tubular Padlock with 7-Pin Cylinder

This American Lock padlock uses a tubular cylinder with seven pins and a rekeyable core. The chrome-plated steel body measures 2 13/32 in high by 1 3/4 in wide and 7/8 in thick. A boron shackle 5/16 in diameter provides a 3 in clearance height and 3/4 in width. The lock is keyed alike to control key number 15546 and carries an American AK5 keyway.

Physical Security Limits of a 7-Pin Tubular Design

Seven pins raise the pick-resistance above basic wafer or four-pin tubular locks, yet the keyway remains a known profile. Boron shackle material resists cutting better than standard hardened steel, but the 5/16 in diameter still fits common bolt-cutter jaws. Weather-resistant construction suits outdoor exposure, though the chrome finish can show wear in abrasive environments. No interchangeable core means the cylinder stays fixed to this body.

Upgrade Path from Standard Keyed-Alike Padlocks

This unit replaces disposable keyed-alike padlocks when the facility needs cylinder rekeying without buying new hardware. The registered control key system adds accountability for master-key holders. The jump is worth it when key control, shackle strength and rekeyability matter together; it is not for buyers who need an interchangeable core system, a different keyway family, or a shackle diameter outside 5/16 in.

Questions about this item

Should I choose this 3-inch shackle height or a shorter version for my hasp?

The 3-inch shackle height clears thick hasps and chains; pick a shorter shackle only if your mounting point is tighter.

What does the 7-pin tubular cylinder mean for everyday security?

Seven pins give a larger key combination space than standard 5- or 6-pin designs, increasing resistance to picking and impressioning.

How does the American AK5 keyway affect key control?

The AK5 keyway is a restricted profile; duplicate keys require authorised registration, limiting unauthorised copies.
