fire door

The FireKing® Model 631 fire-rated service door offers superior protection wherever a listed fire door is required for average size door openings (max. width 14’; max. height 12’). The Model 631 rolling steel fire door is designed for both masonry and non-masonry mounted applications including: facilities with paint booths, file rooms, material storage locations, warehouses, shared walls between businesses, public record storage, and public buildings such as libraries. Customized fire doors are available for conveyor openings.

These doors feature a mechanical auto resettable hoist (non-motorized) that enables easy drop test and reset of the fire door in just seconds. Fusible links are mounted on both sides of the wall that separate to automatically close the door in case of fire.
