Master Lock BumpStop Brass Padlock KA 5 Pin 1-1/2 in Shackle

Brass body with BumpStop security

This brass padlock uses Master Lock BumpStop cylinder technology to resist bumping and picking. It measures 2 5/16 inches high by 2 inches wide by 1 inch thick and weighs enough for solid feel. The 5-pin K6000 keyway accepts key number 10G034 and the lock is keyed alike for convenience. A boron shackle adds cut resistance.

Long boron shackle dimensions

The shackle is 3/8 inch in diameter, 1 1/2 inches high and 29/32 inch wide between the legs. This long-shackle design clears thick hasps, chain links or gate latches that a standard shackle cannot reach. Boron alloy construction resists bolt-cutter attacks better than standard steel. The rectangular brass body is weather resistant for outdoor use.

Check shackle fit and key system

Measure the inside width of your hasp or chain link to confirm the 29/32 inch shackle opening will pass through. Verify the 3/8 inch shackle diameter fits the hole in your hardware. Because the cylinder is keyed alike to 10G034, every lock in the set opens with the same key; order a different keyed-alike group if you need separate access. The core is rekeyable by a locksmith if key control changes later.
