42" x 42" Water Tight Well Hatch - 625psf - Aluminum

42" x 42" BA-BFDWTA Watertight Well Hatch – 625psf - Aluminum

Flooding and water infiltration can wreak havoc on underground utility wells and mechanical spaces. When water seeps through standard hatches, it damages expensive equipment, creates safety hazards, and leads to costly repairs.

Property owners and facility managers know the frustration of dealing with water damage that could have been prevented with the right access solution. The 42" x 42" BA-BFDWTA Watertight Well Hatch – 625psf - Aluminum eliminates these concerns.

Built to withstand up to 10 feet of water pressure, this heavy-duty hatch keeps water out even during severe flooding. The combination of pressure locks and a water-resistant gasket creates a secure seal, while the 625psf load capacity ensures it can handle heavy foot and equipment traffic.

Whether you're protecting utility wells, pump rooms, or any space vulnerable to flooding, this hatch delivers the peace of mind you need.

Why Should You Use the 42" x 42" BA-BFDWTA?

• Submersible and Watertight: Tested to withstand 10 feet of hydrostatic pressure, this hatch keeps water out even when completely submerged. The EPDM rubber gasket creates a reliable seal that protects your equipment and spaces from flooding damage.
• Heavy-Duty Load Capacity: With a 625psf live load rating, this hatch supports pedestrian traffic, maintenance equipment, and more without compromising its watertight seal. The diamond tread plate cover provides excellent traction and durability in all conditions.
• Pressure Lock Security: Type 316 stainless steel pressure locks ensure the hatch stays sealed tight under pressure. These robust latches work with the gasket to maintain watertightness, giving you confidence that your underground spaces remain dry.
• Corrosion-Resistant Construction: Made from 3/16-inch aluminum with a mill finish, this hatch resists rust and corrosion even in wet environments. The Type 316 stainless steel hardware—including hinges, hold open arm, and locks—provides superior durability in harsh conditions.
• Easy Access and Safety: The automatic hold-open arm locks the cover in place when opened, allowing safe, hands-free access to the well below. Heavy-duty stainless steel butt hinges ensure smooth operation even after years of use.
