The KFD-SD is a hinged standard duty floor door for concrete, rated at 300 pounds per square foot. That covers foot traffic, hand carts and stored load, which is what most service openings actually see: pump and valve pits, sump and meter chambers, vault and basement access, stair and equipment openings in plant rooms and back of house floors. Where vehicles cross the opening, the KFD-HD at H20 loading is the door to specify instead.
The door is diamond tread plate in an aluminum extruded frame with integral anchor flanges, so the frame keys into the pour rather than sitting on it. Hinges are stainless steel. The frame is supplied mill finish with a bituminous coating applied to the exterior, which is the face in contact with the concrete and the part that would otherwise corrode first. Diamond tread gives grip on a surface people stand on, and it wears rather than polishing smooth.
Nine standard sizes, 24 x 24 through 72 x 48 inches, with shipping weights from 50 to 158 pounds. The full table with metric equivalents is below. Karp builds floor doors to order and special sizes and modifications are available on request, so send the clear opening, the load case and whether the opening needs drainage, and the sales team will confirm the configuration.
