Gibraltar SC-HML78 7/8" Hinged Memory Lock

The Gibraltar SC-HML78 7/8" Hinged Memory Lock is used to memorize the positioning and height placement of cymbal arms, tom arms, and accessories connected to a rack or stand by a multi clamp so that your set up goes back together the same way every time. The hinge adjustment makes it easy to place and move on a 7/8" diameter cymbal arm, tom arm or accessory arm.
