Hammond RSUS1921BK1 2U Sliding Solid Shelf, 21 in Deep, 114 lb

The RSUS1921BK1 is a 2U solid sliding rack shelf with a 21.00 in (533 mm) deep platform, built for IT, telecom, industrial and AV teams who need to place non-rackmount equipment in a 4-post rack or cabinet and still reach it easily. Mounted on heavy-duty ball-bearing slides, the shelf pulls forward 20.00 in (508 mm) so servers, UPS units, test gear and media devices can be serviced without being lifted out of the rack.

Construction is 16-gauge mild steel finished in a black textured powder coat that is GREENGUARD Gold Certified, TSCA and RoHS compliant. The slides include an integrated stop mechanism that prevents the shelf from pulling completely out during servicing, and are tested to BIFMA standards for a minimum of 55,000 cycles. The part ships as a solid shelf with two 20 in full-travel slides and four slide mounting brackets.

Overall dimensions are 2.68 in (68 mm) high by 18.89 in (480 mm) wide, with a mounting width of 18.36 in (466 mm). The usable shelf surface measures 16.64 in (423 mm) wide by 21.00 in (533 mm) deep with a 1.50 in (38 mm) side lip height. Load capacity is 114 lbs (52 kg); the drawing for RSUS1921BK1 notes a maximum weight of 120 lb.

The adjustable mounting brackets suit rail depths from 12.00 in (305 mm) to 21.00 in (533 mm), so the same shelf fits a wide range of server cabinets and open frame racks. Installation requires two pairs of mounting rails. The shelf itself occupies 2U, but 3U of mounting space must be allowed — it is not designed for product mounted directly above or below.

RSUS1921BK1 is manufactured in North America in an ISO 9001 certified facility and is TAA compliant. A vented version of this size is offered as RSVS1921BK1.
