Bi-Parting: These doors usually have even numbers of leaves and meet at the center of the building opening. They operate by telescoping toward each side of the building opening, typically into door pocket structures located beyond the extents of the opening. The lead leaf of each door group contains the motor operating system and drives the remaining leaves in the group. The doors in a group can be interconnected with the drive leaf by a linear cable sheave system (known as an anchored group) or by a system of pick-up brackets.
Unidirectional: A unidirectional door system is essentially one half of a bi-parting system, where all of the door leaves operate toward one side of the opening. As with the unidirectional doors, the method of operation may be either by linear cable sheave system or by pick-up brackets.
Individually Operated: With any number of self-powered leaves, these doors can move freely to any position in the opening without reference to the jambs or any other door leaf.
Floating Group: These doors have leaves that are interconnected with each other, but are not anchored to the building. These doors can stack and unstack in either direction or move together as a group. These doors are usually interconnected with a linear cable sheave system and have motor operating systems in the door leaves at each end of the group.
