Type FT-30 flood tight floor access doors are constructed for use in applications where there is concern of water or other liquids entering the access opening. Type FT-30 doors are rated to withstand a 30-foot (9.14m) head of water from the topside without leakage and up to a 5-foot (1.52m) head of water from the underside (when specified) and will resist low-pressure gases and odors. Doors are reinforced for AASHTO H-20 wheel loading and feature aluminum construction, type 316 stainless steel hardware, and engineered lift assistance for easy one-hand operation. (Patent Pending) |
