The DC4R4448 is a 44U four-post open frame rack kit built for server, network and IT equipment installations where mounting depth needs to be set on site. Its rails adjust fully from 32 in (813 mm) to 48 in (1219 mm), so one frame can carry short switches or deep chassis servers in data rooms, network closets and homelab builds.
Construction is 12-gauge welded steel rack rails with 1/4" steel base angles, rated for a 2,000 lb static load, and the part is finished in a smooth RAL9005 black powder coat that is GREENGUARD, RoHS and REACH compliant. The underlying material is mild steel, and the rack is TAA compliant and manufactured in North America for government and institutional procurement.
Overall size is 83.13 in x 20.5 in x 48 in (2,112 mm x 521 mm x 1,219 mm), with 44U of EIA-compliant mounting space measuring 77.00 in (1956 mm) high by 19.00 in (483 mm) wide. The base feet extending outwards add approximately 12 inches of overall depth. Shipping weight is 112 lbs (50.80 kg).
Two pairs of 19" EIA-310-D compliant square-hole rails are included, along with marked rack unit dividers and a 50-pack of screws and 10-32 cage nuts. One set of two horizontal cable manager bars supports cable organization, and integrated 10-32 ground studs at the front and rear (two studs per rail) allow bonding and grounding of rack components.
For deployments needing more mounting points or added security, the DC4R4448 accepts extra rails and side panels as the installation grows.
