The C4F307742BK1 is a 44U open cabinet frame from the C4 modular server rack cabinet system, built for data center, enterprise IT and network infrastructure teams that want to configure a cabinet from the frame up rather than buy a fixed assembly. It is supplied as a frame only, with no mounting rails, doors or panels, so integrators can specify the rail style, door style, side panels and top panel that suit the deployment.
Construction is a welded assembly in mild steel: a 14-gauge steel cabinet frame with 12-gauge reinforced corner brackets, finished in RAL9005 Black powder coat. Assembled as a complete Hammond cabinet, the platform is a UL2416 listed rack with a 3000 lb load rating and is seismic rated to a 1200 lb dynamic load (IBC, CBC, NBC, ASCE standards); individual components are not UL2416 or seismic rated on their own. The frame carries cULus and Zone 4 standards references under UL file E474597 and is TAA compliant, manufactured in North America.
Overall size is 83.58 in (2123 mm) high including leveling feet by 30.00 in (762 mm) wide by 42.00 in (1067 mm) deep, with 77.00 in (1956 mm) of usable mounting height and 40.00 in (1016 mm) of usable mounting depth. Shipping weight is 154 lbs (69.85 kg). The 30 in wide frame provides extra generous cabling space and supports up to four optional vertical cable managers, and four 3.50 in (89 mm) cable entry holes are provided on top with cable entry plugs included.
Four leveling feet with 5/16-18 threads are provided, along with a caster mounting pattern, lagging points and 1/4-20 collar studs for panel attachment. Mounting depth is infinitely adjustable using C-channel struts, and grounding and bonding provisions are included throughout the frame for compliant installation of C4F307742BK1.
