Die-cast aluminum cover assemblies: The new Evolution Series poke-thru design includes all metal die-cast aluminum cover assemblies, with two unique spring-loaded slide egress doors. No clumsy flip lids to get broken or cause an added trip hazard. Unique cover design: The cover opens a full 180 degrees with two unique spring-loaded slide egress doors to keep wires, connections and people safe. Flush style cover assemblies: A flush style cover for tile applications allows the Evolution Series Poke-Thru Devices to be adjusted to the same level as the top surface of the floor covering. The flush cover is designed to be used for tile or wood floors and in higher traffic applications, where a low profile is a must. Multiple finishes: Evolution Series Poke-Thru Devices are available in multiple finishes, (BK) black, (GY) gray, (NK) nickel, (BS) brass, (BZ) bronze, (AL) aluminum, (AA) brushed aluminum, (SB) satin brass, and (SN) satin nickel to seamlessly match your environment.
