Hammond RFUS1921BK1 21 in Deep Solid Heavy-Duty Fixed Rack Shelf

The RFUS1921BK1 is a heavy-duty fixed rack shelf with a solid (non-vented) surface, sized 21.00 in (533 mm) deep by 17.75 in (451 mm) wide and 1.94 in (49 mm) high overall. It is part of the RF Series, a high-capacity fixed shelf line designed to support heavy non-rackmount equipment in standard server cabinets and equipment racks, making it a practical choice for IT, telecommunications, industrial and AV installers who need a dependable platform rather than a rail-mounted chassis.

Construction is 14-gauge mild steel with a black textured powder coat finish that is GREENGUARD Gold Certified, TSCA and RoHS compliant. Front and rear flanges measuring 0.81 in (21 mm) increase rigidity and can be installed facing upward so they act as integrated equipment retainers, helping keep gear from sliding during servicing or transport. Folded side flanges add strength and let hardware be installed from above, and slotted side mounting (0.250 x 2.000 in slots) accommodates a range of rack rail depth positions.

Rated for a maximum load of 350 lb (159 kg), RFUS1921BK1 suits UPS systems, battery backups, non-rackmount servers, network appliances, industrial controls and test equipment. Shipping weight is 11.9 lbs (5.40 kg) and all required mounting hardware is included.

To mount this shelf you must have two (2) pairs of combination rails in the cabinet. For installation in a traditional equipment rack, order the FSRA Fixed Shelf & Accessory Rail Adapter; for cabinets using Hammond CPR square-hole rails, order one CPRSA Square Hole Rack Rail Shelf Adapter per shelf. The shelf is manufactured in North America in an ISO 9001 certified facility and is TAA compliant, USMCA compliant, RoHS and REACH compliant. A vented version of this size is available as RFVS1921BK1.
