Hammond RB-HFMD4 4U Horizontal Finger Cable Manager With Cover

The RB-HFMD4 is a 4U horizontal finger cable manager with a removable cover, built for structured patch-cable routing in standard 19-inch EIA-compliant racks. It suits IT and network technicians, AV and broadcast integrators, and structured cabling crews who need cables guided into defined pathways instead of bundled loosely between switches and patch panels.

Construction is 16-gauge steel with polycarbonate fingers. The fingers are UL94V-0 rated for flame resistance, and the steel is finished in black powder coat that is GREENGUARD, TSCA and RoHS compliant, supporting indoor air quality and environmental compliance requirements. The unit ships pre-assembled as a two-piece design: an HFMD 4U back and an HFMD 4U cover. The cover snaps over the fingers to conceal cables for a clean appearance and improved airflow management.

RB-HFMD4 measures 6.97 in (177 mm) overall height by 19.02 in (483 mm) wide by 6.54 in (166 mm) deep, with a 7.00 in (178 mm) usable 4U mounting height and 18.32 in (465 mm) 19-inch mounting width. Inside dimensions are 6.33 in (161 mm) and 5.88 in (149 mm). A top cable pass-through measures 1.45 in (37 mm) by 4.47 in (114 mm), and the rear cable pass-through is 5.00 in (127 mm) by 3.60 in (91 mm) for routing flexibility. Shipping weight is 5 lbs (2.27 kg).

Mounting hardware is not included. Managers in this series can be installed back-to-back for double-sided cable management in high-density racks. This part is TAA-compliant and manufactured in North America (country of origin CA), making it suitable for government procurement, and is part of the Rack Basics line for simple, reliable installations.
