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. All of our discharge doors are equipped with a 1-1/2 hour fire damper with UL listed fusible link designed to melt when the ambient temperature of a fire reaches 165 degrees. This action closes the door to stop fire from traveling up the chute into the building 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.
