Premise Wiring S1SP Poke Through Sub Plate Systemone

Product Description

The PREMISE WIRING S1SP is a modular sub plate designed for use with SystemOne floor boxes and poke-through assemblies. Measuring 5.36 inches in diameter and 0.22 inches in height, this flush-mount plate accepts two Style Line Decorator or GFCI devices and features a powder-coated black finish. It installs into a universal SystemOne cover, giving contractors and specifiers the ability to configure application-specific combinations without replacing the entire assembly. Mounting hardware is included. The S1SP carries UL approval for both the United States and Canada.

The S1SP is intended for commercial and institutional installations where SystemOne floor boxes or poke-throughs are already in place. The modular design allows existing floor box systems to be reconfigured or upgraded to accommodate future layout changes, device additions, or wiring updates without full fixture replacement. This plate is a practical solution in office environments, conference rooms, and open-plan spaces where floor-mounted power and data access points require periodic reconfiguration. Licensed electricians performing floor box rough-in or finish work are the typical installers.
