Flush Style Poke-Thru devices are an excellent solution for bringing power, communication and audio/video services to the workstation in an open space, above-grade floor environment. All Wiremold® Flush Style Poke-Thru devices come with built-in TopGuard™ protection, an industry-leading design that meets and exceeds UL scrub water exclusion requirements for tile and carpet floors. TopGuard™ protection prevents water, dirt or debris from entering not just the power devices, but also the communication devices.
