72" x 72" BAC-DDRHGA Double Leaf Domed Aluminum & Steel Equipment Hatch
Lifting heavy equipment through a standard roof hatch can be a real hassle. A bulky cover is frustrating, slows the job down, and even causes injuries. When equipment needs to be moved to or from the rooftop, the last thing anyone wants is a difficult, time-consuming process.
The 72" x 72" BAC-DDRHGA Double Leaf Domed Equipment Hatch makes access easier and safer. Its dual-cover design splits the weight, so you’re not wrestling with a single heavy lid. Plus, the built-in lift assist springs help open the hatch smoothly, reducing strain and effort.
From installing new equipment to handling routine maintenance, this hatch makes the job easier from start to finish.

Installation Instructions
- Prepare the Roof Opening: Cut an opening in the roof deck that matches the hatch size, measured from inside curb to inside curb. Ensure the opening is properly positioned without compromising the roof’s structural integrity.
- Position the Hatch Securely: Place the hatch over the opening, ensuring it sits flat and level. Shim if necessary to prevent twisting or misalignment.
- Fasten the Hatch to the Roof: Use appropriate fasteners to secure the curb flange to the framed roof opening. For wood frames, use #10 screws, or drill larger holes for bigger bolts as needed.
- Complete Installation & Final Checks: Finish roofing around the hatch per local building codes. Remove safety bands from the door sides, and handle with care—spring-loaded doors may pop open if latches shift during shipping.
