Description These steel brackets are used to support a swing-up shelf that locks in position at working height. To lower, just lift a bit past the raised position to release the lock. Installed in a cabinet at least 19" deep, they accommodate objects 16" high, with a depth of 16" (no limit on shelf width). Useful for mixers, blenders, or any other object that's awkward to handle. Maximum recommended load of 44 lb.
