2-hour fire-resistant "large-diameter machine hatch"
It is a large-diameter machine hatch with a fire resistance of 2 hours.
Since it meets the performance criteria for a fire-resistant structure (floor) of 2 hours, it also possesses "1-hour flame resistance." Due to the integrated structure of the lower cover and fire-resistant cover, the height of the product is minimized, allowing it to adapt to various slab heights. The fire-resistant hatch is compatible with all large-diameter machine hatches (excluding extra-large diameter machine hatches).
