Hammond DNRMV1924BK1 3U Vented Rack Shelf, 24-Inch Deep, 300 lb

The DNRMV1924BK1 is a 3U vented rack mounting shelf sized for 19 inch racks with a 24.00 in (610 mm) mounting depth. It is designed for use with heavy-duty DNRR and DRZ4 double-tapped two (2) post racks, or any 2 post rack, making it a practical equipment platform for IT, AV, telecom and electrical installers who need to support non-rackmount gear, batteries or other heavy components inside an open frame rack.

Construction is heavy-duty 16 gauge mild steel finished in textured RAL9005 black powder coat, a finish that complies with the Greenguard guidelines for indoor air quality. The vented deck provides a sturdy shelf without obstructing upward heat movement, while the folded front and rear lips add strength and act as equipment retainers. The series is load rated to 300 lbs (136 kg); the part drawing for this shelf states a maximum weight load capacity of 275 lb, so verify the figure that applies to your installation.

Mounting dimensions are 3U / 5.25 in (133 mm) high by 19.00 in (483 mm) wide by 24.00 in (610 mm) deep. The drawing shows an overall shelf depth of 24.00 in (610 mm) with a 20.00 in (508 mm) deck dimension, a 19.00 in (483 mm) front width, and a 1.50 in (38 mm) lip height. Venting is by 0.19 x 1.00 slots across the deck.

DNRMV1924BK1 ships with four mounting brackets, eight 10-32 x 1/2 screws and eight 10-32 KEP nuts, with mounting hardware included for both 10-32 and 12-24 rails. The shelf is RoHS and REACH compliant, USMCA compliant, TAA-compliant for federal GSA schedule purchases within the USA, and manufactured in North America.
