Square caps and slotted panel bracket take a unique approach to traditional standoff display. Mount glass or display panels without drilling through them. Outer barrel shell mounts to the wall, then the panel is set in place on the inside of cap in the slotted inner barrel. A set screw is tightened to hold the panel tight against the cap. The inner barrel slides into the outer barrel and once tight up against the display, another set screw is tightened from the outer barrel to hold the entire assembly in place. Holds materials from 1/8" to 1/2" thick.
