Hammond C2T1936VBK1 20 x 28.25 in Vented Cabinet Top Panel, Black

The C2T1936VBK1 is a vented cabinet top panel from the C2TV Series, designed to provide passive airflow for rack cabinets in data centers, IT rooms, network and telecom installations, AV and broadcast environments, and structured cabling deployments. It replaces a solid top panel where additional ventilation is needed, letting heat escape naturally from the top of the cabinet without adding active fan systems.

Construction is 14-gauge mild steel with a black powder coat finish (RAL9005 black; the drawing identifies the finish as painted black textured). The powder coat is GREENGUARD, TSCA and RoHS compliant, supporting indoor air quality and environmental compliance goals. The part is RoHS, REACH and USMCA compliant, TAA-compliant and manufactured in North America, which helps satisfy government procurement requirements.

Overall dimensions are 20.00 in (508 mm) wide by 28.25 in (718 mm) deep, with a shipping weight of 6 lbs (2.72 kg). This panel size is intended for a C2 cabinet measuring 23.00 in wide by 36.00 in deep, or a C4 cabinet measuring 24.00 in wide by 42.00 in deep. The C2TV Series is designed for use with C2, C2RR, C4, C4RR_A, C4RR_S, C4RR_D, H1, RCK or CLC cabinet series; H1 cabinets require the H1TC Series for mounting.

C2T1936VBK1 is the non-cable-entry version of this size, so the panel has no corner grommet openings; if cable entry through the top is required, the C2T1936VCEBK1 variant includes openings in all four corners. Mounting hardware is included in the box: six 8-32 clip nuts with black oxide finish and six 8-32 x 0.5 in zinc-plated machine screws (replacement kit CLPKIT832-6), so installation can be completed without sourcing separate fasteners.
