TRIPP LITE's N060-004 heavy duty 14-gauge steel, 4U (7.0 in) wall mount patch panel bracket, is the ideal alternative to a full size rack. Standard EIA 19 in width allows installation of any 19 in patch panel. Laser cut metal ( not punched ) keeps all edges smooth, greatly reducing the possibility of injury, and, wear on cable jackets. Universal mounting for right or left hinging. Keyholes are spaced 16 in for mounting on wall studs. Stamped, horizontal reinforcement ribs allow for greater sturdiness and stability, and allow the addition of a rear cutout for feeding cable through a wall opening. Smooth, glossy black finish.
