locker lock with key

Keyed locker padlocks use several mechanisms, including double-locking lever, pin-tumbler, and warded locking designs.

Shackle lengths shown range from about 11.0 mm (7/16 in.) up to adjustable lengths of 51 mm (2 in.). Reported shackle diameters and related width measurements include about 5/32 in. (4 mm) up through values listed as 40 mm.

These keyed padlocks are made from a mix of metals and finishes, including laminated steel, hardened steel, brass, iron, and vinyl-covered aluminum bodies for scratch and corrosion resistance.

Small keyed luggage locks measure roughly 0.7 x 1.2 x 0.25 inches (1.2 x 0.7 x 0.25 inches) and are described as ideal for zippers, jewelry boxes, diaries, and other small containers.

A warded locking mechanism is described in the results as minimizing jamming from dirt and grime.

Adjustable shackle locks in these results offer ranges from about 5/8 in. (16 mm) up to 2 in. (51 mm).
