Padlock

SmoothSpin, a new product from Master Lock, is a durable die-cast combination lock with a zinc body that can be opened with one hand. The lock is made specifically to accommodate fingertip twist or thumb-turn dialing.

A hardened steel shackle can resist cutting and prying and its 40-number dial allows for thousands of possible combinations. The lock is designed with shackle tension to prevent break-ins and the combination automatically scrambles once the shackle is in place. A control key provides access in case of a forgotten combination or if emergency access is needed.

The lock also has a dial shield to reduce possible injury in case of an attack. It is designed to fit lockers with a 5/16-inch padlock eye diameter. It comes in several colors including black, blue, red, green and purple.
