Clopay doors are balanced by torsion (shown) or extension springs. Extension springs are mounted just above the horizontal track, perpendicular to the closed garage door. Torsion springs are mounted above the closed door, parallel and horizontal to the top section of the door as shown here. Torsion springs wind and unwind to provide lifting power, where extension springs get their lifting power by stretching.
Sections are the primary visual part of your door. Clopay offers a wide variety of exterior door designs. Interior construction ranges from pan doors without insulation to insulated steel sandwich doors.
Heavy gauge steel is used to ensure stability and long life. All Clopay track is made specifically for every door ordered and can be adjusted for a precise fit.
Hinges are made of high-quality steel and bear the weight of the door in the upright (closed) position. Hinges are powdercoated for maximum protection against moisture and rust.
Clopay uses steel wheel ball-bearing rollers for smoother, quieter operation. Clopay garage doors offer nylon rollers with steel ball bearings for superior noise reduction-a plus when living space is used above or in close proximity to the garage.
To help keep out wind and rain, Clopay garage doors feature a vinyl bottom weatherseal attached to a sturdy aluminum retainer.
These sensors are mounted five to six inches off the floor on either side of the door. Working in conjunction with the garage door opener, photo eyes send an invisible beam across the door opening. If the beam is broken while the door is operating, the door will reverse direction and return to the open position.
