The outriggers add depth and interest to wall presentations and are a great alternative to traditional perimeter wall systems. Each unit is 90" tall with 1/2" slots on 1" centers. This outrigger is constructed of heavy duty 1 1/4" diameter plumbing pipe. Plumbing style flanges anchor uprights to wall with a 3 1/2" standoff. The outriggers feature a matte black finish.
