• 【Strong Galvanized Metal Roof Skylight Cover】Made with an aluminum alloy frame and galvanized steel sheet, it is lightweight, using 1mm thick galvanized steel sheet and an aluminum frame
• 【Weatherproof Sealing】Our roof skylight frame integrates rubber gaskets to form an airtight barrier, preventing wind and rain from seeping in. This advanced sealing system also improves sound insulation and thermal efficiency, thus enhancing indoor comfort and saving energy
• 【Hydraulic Soft-Close System】Featuring a precision hydraulic hinge design, the cover opens smoothly and remains stable in any position. The controlled closing mechanism eliminates the risk of pinching fingers by gently lowering the cover—no more dangerous "bang."
• 【Sealing Strip and Handle Design】The aluminum frame incorporates a sealing strip with excellent weather resistance. It prevents rainwater from seeping into gaps. The thoughtful handle design makes opening and closing easy (the roof access door can only be opened and closed from the inside, not from the outside)
• 【Multi-functional Skylight】Not only can it be used as an attic skylight cover, but it can also be used as an escape hatch cover, basement exit cover, emergency access cover, well cover, cellar cover, and manhole cover
