No need to unplug your cords from your power strip, simply place it directly in the box and run the cords through the openings on the sides. The high density, flame-retardant plastic and non-slip grip make the CableBox the safest and most functional tool to hide your cable tangles. The interior dimensions are 15.75" L x 5.75" W x 4.25" H and the exterior dimensions are 16" L x 6.25" W x 5.25" H.
