Fire-Rated Horizontal Chute Discharge Doors

fire-rated horizontal chute discharge doorfire-rated horizontal chute discharge doorHorizontal, open-end, trash or linen chute discharge doors feature a Class “B”, 1½-hour, 250º UL labeled Fire Damper. All of our discharge doors are equipped with a 165º replaceable, fusible link designed to melt in the event of fire. These doors slow or stop fire from traveling up the chute into the building for the listed time and feature a replaceable accordion-style fire damper insert.

Designed for standard size square or round chutes, we can also accommodate your custom sized chute! If your discharge door is too far from the collection bin, look at our extension collars that fit these discharge doors. Our discharge doors comply with building codes for use as a fire damper. These doors are not tested by UL for use as a horizontal chute-type fire door, as UL does not have such testing available. Therefore a UL labeled horizontal, accordion, snap-action fire damper is offered.
