Hammond SDCSR9 9U Square Hole Rack Rails for SDC Cabinets

SDCSR9 is a set of 9U square hole mounting rails for Hammond SDC Series multi-mount wall-mount rack cabinets. It is intended for IT, telecom, AV and low-voltage installers who need square-hole (cage nut) rails in place of, or as replacements for, the rails in a 9U SDC enclosure so that standard 19-inch rack equipment can be mounted with 10-32 cage nuts and screws.

Each rail is fabricated from mild steel with a black smooth painted finish, and the SDC Series uses 12-gauge rails for durable, high-strength support of rack-mounted gear. The rail face carries repeating 0.375 in x 0.375 in square cutouts on typical E.I.A. spacing, with each rack unit measuring 1.25 in (32 mm), giving 9U of usable mounting height. Two 0.31 x 0.50 slots are provided in the mounting flange.

Overall size of a single rail is 15.78 in x 1 in x 3.04 in (401 mm x 25 mm x 77 mm), with a 14.62 in (371 mm) hole pattern length and a 3.07 in typical rail-to-rail reference on the drawing. Shipping weight for the SDCSR9 set is 6 lbs (2.72 kg). Mounting hardware is included.

Note that the part description lists SDCSR9 as a pair, while the drawing notes the SDC square hole rail is sold in a set of 4 (quantity 4 shown); confirm the quantity required for your cabinet configuration. SDCSR9 is made in Canada, USMCA compliant, TAA-compliant, and RoHS and REACH compliant, making it suitable for government, education and enterprise projects with sourcing and environmental requirements.
