BA-WTFD-H20

The BA-WTFD-H20 is a watertight floor hatch built for indoor and outdoor off-street locations that may occasionally receive AASHTO H 20-44 wheel loads.

Its aluminum channel frame is cast directly into concrete, with drainage routed through a threaded coupling built into the frame. The 1/4" aluminum diamond plate door is reinforced to handle 16,000 lb. wheel loads with 30% added for impact.

An automatic hold open arm locks the door at 90 degrees, and a flush aluminum drop handle with stainless steel slamlock secures it when closed. This gives maintenance teams a durable, weather-resistant access point in floor slabs where vehicles or heavy equipment occasionally pass overhead.

Why Do Contractors Choose BA-WTFD-H20 Watertight Floor Hatch with H20 Loading?

• Keeps water and dirt out: The watertight plug, odor reduction gasket, and 1-1/2" drainage coupling in the channel frame prevents water and debris from reaching the work area below.
• Built for H20 wheel loads: The 1/4" aluminum diamond plate door meets AASHTO specification H 20-44 for traffic loading for off-street locations that occasionally receive vehicle traffic.
• Corrosion-resistant hardware: The door and frame are while the hinges, nuts, bolts, springs, and the hold open arm are 316 stainless steel. This makes the panel corrosion resistant.
• Secure when closed and easy to open: A flush aluminum drop handle with stainless steel slamlock secures the door. The automatic 316 stainless steel hold open arm locks the door at 90 degrees for hands-free access and controlled closing.
• Cast into the slab: The aluminum channel frame has a 1-1/2" drainage coupling and an integral 1" anchor flange designed to be cast into concrete. Bituminous coating is applied to the area of the frame in contact with concrete.
