Middle Atlantic GO-144-AL Overfloor Wireway
Overview
The GO-144-AL is a flat, low-profile overfloor wireway from Middle Atlantic's GO series, measuring 5 in wide x 0.65 in tall x 12 ft long. At just 0.65 in high, it sits nearly flush with finished floors — the right choice when cables must cross open walkways in conference rooms, control rooms, or AV equipment bays without creating a trip hazard or requiring trenching. The GO-144-AL designation encodes the channel's 144-inch (12 ft) run length, giving you a single continuous section that spans most room widths without a mid-run joint. TAA compliance makes it eligible for government and federally funded installations where country-of-origin sourcing restrictions apply.
Compatibility
The GO-144-AL is part of Middle Atlantic's GO overfloor wireway family. It is dimensionally compatible with other GO-series components including straight sections, reducers, couplers, and end caps from the same product line. The 5-in channel width accommodates standard low-voltage cable bundles — network patch runs, HDMI or HDBaseT signal cables, and security camera home-run cabling are all practical fits. Verify channel fill against your actual cable bundle diameter before ordering; Middle Atlantic also offers narrower GO-series profiles for lighter cable loads. For installations requiring power and signal distribution from rack-mounted equipment to floor-level endpoints, pair with Middle Atlantic rack systems and cable management accessories for a coordinated pathway solution.
Installation Notes
The 74 x 11 x 3 in shipping carton reflects the 12-ft section length — confirm door clearance and staging space before delivery. The wireway installs directly on finished flooring; secure with appropriate adhesive or mechanical fasteners per the substrate type (concrete, raised floor tile, carpet). No special tooling is called out in the manufacturer specifications. Miter or cut sections to length with a fine-tooth saw to maintain a clean edge at transitions.
