Overview
The Wiremold RC3ATCAB is a fully assembled, multi-service flush poke-thru device from Legrand’s RC3 Series, designed to bring power and communication services directly to open-space workstations through above-grade concrete floors. Installed in a 4-inch (102–105mm) core-drilled hole, this device delivers a 20A duplex receptacle and four keystone communication ports in a single unit — eliminating the cost and disruption of running multiple poke-thru assemblies. The brushed brass flange and brass-colored nonmetallic slide covers integrate cleanly into commercial interiors with a premium finish. Country of Origin: Mexico.
