Standard Lift

Standard lift is the default track configuration specified for most residential and light commercial sectional garage doors. In a standard-lift installation, the door moves straight up along the vertical track mounted to each jamb, transitions through a curved radius section at the top, and then travels horizontally into the garage along the overhead horizontal tracks. When fully open, the door hangs parallel to the ceiling above the garage floor.

The radius section is the bent portion of track that connects the vertical run to the horizontal run. It comes in 12-inch and 15-inch radius sizes. The 12-inch radius is more common in residential work where ceiling clearance is limited. The 15-inch radius is smoother for the rollers and is preferred when headroom allows.

Headroom requirements:

Standard lift needs approximately 10 to 15 inches of vertical clearance between the top of the door opening and the ceiling or first obstruction. This space accommodates the radius bend, the horizontal track, and the partially coiled door sections as they transition from vertical to horizontal. The exact requirement depends on the track radius size and the section height of the door.

When headroom is less than standard allows, a low-headroom track configuration is required instead. When the ceiling height exceeds what standard lift can use efficiently, a high-lift configuration extends the vertical run before bending overhead, allowing the door to stack higher on the wall instead of taking up ceiling space.

Standard lift is the configuration used with most torsion spring setups. The spring is wound to counterbalance the door weight as the cable drum takes up cable during the vertical rise. The flag bracket at the top corner of each vertical track connects the vertical and horizontal track sections and is the hardware that defines the geometry of the standard-lift radius bend.

A standard-lift door in a 7-foot-high opening, for example, would have its horizontal track running at roughly 7 feet 10 inches to 8 feet above the floor, depending on the radius. This determines how much overhead storage space remains available in the garage.
