Pass and Extended Biparting Door

Pass-type Doors consist of an upper and a lower panel of equal height, with the upper panel being offset, making room for the door panel above to slide in front of “or pass” the offset panel. In this situation, the lower panel will be constructed with a wider trucking sill. This is called an extended sill. This extended sill will need to be included on all doors in the same line.

Pass doors also require a Fire Lintel that closes the gap between the upper panel and the wall. Fire Lintels are designed to pivot down when they come in contact with the panel above.

Pass-Type Doors are used when there are limited floor-to-floor heights.
