August 5, 2009--While Wiremold/Legrand's Evolution Series poke-thru devices are designed to be installed in 6" or 8" holes in the slab, instead of core-drilling these holes after the slab is poured, contractors can now take advantage of Evolution Pre-Pour Sleeves.
These PVC sleeves attach to the structural decking and maintain a 6-1/8" or 8-1/8" cast-in hole. Each unit includes three attachment legs, thumb screws, and end caps. After the pour, the contractor removes the pre-pour sleeve and installs the Evolution poke-thru device in the hole. (The sleeve, which is not a fire-classified product, must be removed.)
Evolution Series poke-thru devices are UL-fire classified to maintain the fire rating of the floor slab for up to two hours. They are designed to offer more space for receptacles and activations as well as to allow the entire device to be recessed below the finished floor level.
