The KeyRack Locker utilizes the same sturdy stainless steel S-biner body used on the KeyRack and the KeyRack Steel, but uses a locking version of the S-Biners to hold the keys in order to prevent any chance of them disconnecting accidentally. Other than the sturdy polycarbonate locking levers, the construction is entirely of stainless steel. Each of the six locking S-Biners can typically hold up to three keys, while the larger S-Biner clip on the body allows for securely attaching the KeyRack Locker to a belt loop, backpack strap, another key ring, or any other convenient spot. The KeyRack Locker measures 3.05 x 0.6 x 1.25 in (77.5 x 15.5 x 32 mm). Comes in stainless (silver) finish.
