This aluminum corridor bracket is designed for perpendicular wall mounting to increase visability. It holds personalized plastic inserts and supports single-sided signage using one 1/8" insert or double-sided signage using two 1/16" inserts positioned back-to-back. Two nuts and two bolts are included for sign attachment to the bracket. Wall mounting hardware is not included. The listed depth indicates how much of the plastic insert slides into and is covered by the bracket.
