Hammond VFMMD12WH 12 in Wide 44U Double-Sided Vertical Cable Manager

VFMMD12WH is a double-sided vertical cable manager with a high-density finger duct, built for open frame rack systems in data centers, network closets and telecom rooms. It routes cables on both the front and rear of the rack, creating a centralized cable management spine between ganged racks so fiber and copper patch cables can be distributed across an entire row.

The manager uses a 16-gauge steel frame with a finger-style duct that organizes cables at each rack unit. Metal fingers are spaced at 2U intervals and are fitted with clip-on plastic finger guards (shipped loose) that maintain bend radius for fiber, Cat6/6A and coax, reducing strain on large or heavy-gauge bundles. Full-height removable covers contain the cables for a clean installation; this part number ships with dual hinged doors (one 3-piece and one 1-piece 12 in wide door) plus mounting hardware. The finish is painted textured white.

Overall dimensions are 81 in x 12 in x 24.5 in (2,057 mm x 305 mm x 622 mm), with 77.00 in (1956 mm) of mounting height equal to 44 rack units. The extended 24.5 in depth adds usable cable space compared with standard-depth vertical managers. At 12 in wide, estimated fill for VFMMD12WH is 1,080 Cat 6 or 750 Cat 6a cables in the combined front and rear channel openings at a 50% fill ratio, and 2,162 Cat 6 or 1,502 Cat 6a at 100%.

Managers in this series are designed to mount to racks rather than sit directly on the floor, with a plinth base option available for end-of-row positions. Accessory inner panels, cable spools and dividers are available in the 12 in width, and cable spool mounting slots are provided in the body. VFMMD12WH is TAA-compliant, made in Canada, and RoHS and REACH compliant.
