Invented by Pizazz, multi•mounts are designed to display changeable graphic images on walls and other surfaces in various graphic display applications. Pizazz multi•mounts have three Parts, A+B+C, which are sold together as a set. Optional extra•spacers, D Parts - are also available and are sold separately. extra•spacers can increase the standoff distance and hold more panels, giving you more creative options, including multilayering and offsetting some panels.
