With Sobo heavy duty padlocks you can be assured of the high security and durability our locks will provide. Feel the solid weight in your hand. Turn the key, or realase the shackle and note that the motion is smooth with no spring loaded parts to bind or wear out over time. The SPSA series grants very little access for bolt cutters or saws, and features a hardened steel, chrome plated bolt that rotates freely  indeed making this lock live up to its name as a "Jimmy Proof" style padlock.
