KeyRack Locker features sturdy, secure carabiner gate closure for clipping keys onto and off belt loops, zipper pulls, purse straps, second key rings - anything with a loop or D-ring. The bottom half encompasses a solid loop that holds six S-Biner MicroLock carabiners that feature a center locking lever. A simple twist securely locks the gate and keeps it that way until it is twisted open. A single key can be removed from the ring to carry, give to mechanic or valet, or leave for a friend.
