Installer Friendly Advantages
Offers several installer-friendly advantages, including an expanded 6RU opening in the cabinet top and bottom which can be left open for wire access and/or ventilation, or closed using a standard vent or solid panels.
Rear doors (included with all models) are hung with quick-release spring hinges which allow them to be rotated 180-degree for right or left-hand opening. If a front door is ordered, it will be keyed differently than the rear door for security.
Rack rails are precision tapped 10-32 and recessed 11/16-inch (17.5mm). These plated rails include convenient RU indicator hash marks to aid in equipment alignment. Rails are standard E.I.A. 5/8-5/8-1/2-inch spacing.
Conduit arrays are located on the top and bottom surface panels, as well as the top and bottom back flanges. Flange arrays consist of five knockouts, three 1-inch (25 mm) standard, and two 1/2-inch (13 mm) x 3/4-inch (19 mm) concentric. Surface arrays are comprised of 4 knockouts, two, 1-inch (25 mm) standard knockouts and two 1/2-inch (13 mm) x 3/4-inch (19 mm) concentric.
Maximum Air Circulation and Phosphate Pre-Treated Surface
Stamped, perforated vents are located on all sides as well as on the rear door to allow for maximum air convection. Cabinet surfaces are phosphate pre-treated for proper paint adhesion of the textured black epoxy finish.
