The design for the aluminum floor doors of the A-FPS Series is excellent for indoor and outdoor flood-tight situations where water may rise over the opening's surface. Bolting to concrete is possible because of the angle frame's 4" high horizontal leg. The diamond plate door panel is 625 pounds per square foot strengthened (capable of holding up to 10 feet head of water). The door panel overlaps the frame, squeezing the gasket and ensuring a leak-proof seal.

Other features you can find include:

Material: Aluminum door & frame, type 316 Stainless steel hinges & hardware.
Lock/Latch: Type 316 stainless steel pressure lock system and exterior staple for padlock.
Flange: 3/8 aluminum with 4 high raised frames for bolting to concrete.
Hinge: 316 stainless steel butt hinges with tamper-proof stainless steel bolts and nuts.
Finish: Mill finish with a bituminous coating applied to the exterior of the frame.
