Garage Door Installation Garage doors can be classified a few different ways. In this project, we'll install a sectional door with extension springs.
Trackless doors have one-panel that lifts open, out and up using hinges.
Torsion springs are installed under high tension and need to be handled by a professional. Extension springs are located on each door side above the top tracks. An appropriate header and trimmer studs are needed to support the span of the garage door opening. Top, side and back jambs fasten to the framing to complete the rough opening. Install the header jamb first.
