24" x 24" BA-WTFD-H20 Watertight Floor Door with H20 Loading – BEST

Managing heavy traffic in off-street locations requires a floor hatch that can handle more than just foot traffic.

The 24" x 24" BA-WTFD-H20 Channel Frame Floor Door is engineered for areas that occasionally receive AASHTO H20-44 wheel loads. This makes it ideal for loading docks, manufacturing plants, and distribution centers where heavy machinery or vehicles may pass over the access point.

The door is constructed from a 1/4" aluminum diamond plate reinforced to handle a 16,000 lb. wheel load and meet strict AASHTO specifications for traffic loading.

The channel frame is designed to be cast into concrete and features a 1-inch anchor flange. It also includes a 1-1/2" drainage coupling that directs water and debris away from the internal compartment to keep the work area below clean and dry.

Safety and ease of use are central to the BA-WTFD-H20 design. It features a flush aluminum drop handle and a stainless steel slam lock for secure, trip-free access. The door opens 90 degrees and automatically locks in place with a hold-open arm, allowing for safe entry and exit.

For larger models, units 48” x 48” and above use a double-leaf design to maintain door weight and maximize clearance.

Why Should You Choose the 24" x 24" BA-WTFD-H20 Watertight Floor Door?

• AASHTO H20-44 Load Rating Approved: Reinforced to withstand a 16,000 lb. wheel load (plus 30% for impact), the door is ideal for areas where heavy vehicles occasionally operate.
• Effective Drainage: The 1-1/2" threaded drainage coupling removes water and grime quickly, keeping the area below clean.
• Superior Corrosion Resistance: The mill-finished aluminum and stainless steel make the door naturally rust-resistant, which is ideal for outdoor or damp indoor use.
• Tamper-Proof Security: The door features stainless steel butt hinges and tamper-proof fasteners, combined with a stainless steel slam lock, so that only authorized personnel can access the utilities below.
• Automatic 90-Degree Hold-Open: The hold-open arm holds the door leaf securely at 90 degrees to provide hands-free access and prevent the door from closing unexpectedly during maintenance.

Keep your heavy-duty access points safe and compliant with a professional solution built for high-traffic industrial sites. Call +1-888-327-5471 to discuss how we can incorporate the BA-WTFD-H20 Watertight Floor Door into your next project.
