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.
