The Dynacom hinged patch panel brackets are made of cold-rolled steel and are rigorously tested to ensure the highest quality. They are an ideal alternative to a full size rack and require much less labor to install. Mounting is very easy, requiring only 4 screws and can be used either left or right hinging. The mounting holes are spaced 16 inches apart for mounting onto studs. The hinged brackets come in 5 sizes: 1.75" (1U), 3.5" (2U), 5.25" (3U), 7" (4U) and 10.50" (6U) and fit to any industry standard 12, 24, 48, and 96 port patch panels.
