Material: Our roof skylight covers are made of 1mm thick galvanized steel plates and aluminum frames, which are sturdy, resistant to deformation, and have strong load-bearing capacity.

Good sealing: All roof inspection hatches are equipped with built-in rubber seals to prevent rainwater from seeping in through gaps. The thoughtful handle design makes opening and closing more convenient.

Anti-pinch Design: This roof maintenance skylight is fitted with two hydraulic support rods that allow the top to close slowly, fingers from being pinched. The support rods on this galvanized powder-coated steel roof skylight can control the maximum opening angle of the skylight cover to 90 degrees.

Easy Installation: The roof access hatch comes with expansion screws, enabling quick installation in just a few minutes. Place the manhole cover on the hole seat, then drill holes, insert the expansion screws, and tighten them.

Multi-functional use: This aluminum alloy roof access hatch cover offers exceptional flexibility. The hatch cover can serve not only as an attic skylight cover but also as an escape hatch cover, basement exit cover, emergency access cover, manhole cover, cellar cover, and manhole cover.
