The C2F194931BK1 is a 28U open cabinet frame from the C2 Series modular rack cabinet system, supplied as a frame only with no mounting rails. It is intended for integrators and engineers who want to build a cabinet to their own specification for AV, telecom, lab, test and measurement, or general equipment installations, selecting the rails, panels, doors and accessories that suit the job.

Construction is a 14 GA steel welded assembly finished in RAL9005 black textured powder coat. Across the C2 platform the frame uses 12-gauge reinforced corner brackets with 16-gauge doors and panels, and the system carries a 1500 lb load capacity. Grounding studs on the frame, doors and panels support bonding, and the textured powder coat finish is GREENGUARD, TSCA and RoHS compliant.

Nominal size for this part number is 56.31 in x 23 in x 31.5 in (1,430 mm x 584 mm x 800 mm), with the series ordering table listing overall dimensions of 57.16 in high, 23.00 in wide and 31.50 in deep. Usable mounting height is 49.06 in (1246 mm) for 28 rack units, with usable mounting depth listed as 29.50 in (749 mm) in the ordering table and 29.84 in (758 mm) on the drawing. Shipping weight is 104 lbs (47.17 kg).

Because C2F194931BK1 ships without rails, pair it with 19 in rack rail pairs: CCR49TZPL for tapped 10-32 threaded rails or CPR49SZPL for square hole rails. Infinite-depth rail adjustment using C-channel struts allows equipment mounting depth to be set as needed. Four leveling feet are included (5/16-18 thread) with 1/4-20 caster hardware provisions and Ø.50 in (13 mm) lagging points for bolt-down or mobile installations.

The frame is made in Canada, TAA compliant, USMCA compliant, and RoHS and REACH compliant.
