Garage doors are balanced by torsion 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 power by stretching. 99% of the garage doors that Raynor installs uses a Torsion system.
Sections are the primary visual part of your door. Raynor Doors of Nebraska offers a variety of exterior door designs, including up to 15 different exterior styles for doors. Interior construction ranges from pan doors without insulation to insulated steel sandwich doors that can reach an insulation R-value of up to 18.0.
Heavy gauge steel is used to ensure stability and long life. All Raynor track is made specifically for every door ordered and can be adjusted for a precise fit. There is also a powdercoated finish that can be applied for an extra charge that can make your track look detailed and painted.
Hinges are made of high-quality steel and bear the weight of the door in the open and closed position. They are installed on the back (inside) of the door to hold each section together. The wider the door, the more hinges will be installed.
Raynor uses steel wheel ball-bearing rollers for smoother, quieter operation. Raynor Premium-level 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, Raynor garage doors feature a vinyl bottom weatherseal attached to a sturdy aluminum retainer. Side and top seals are also included in all door installations, to keep out all of the elements from getting into the garage.
These sensors are mounted five to six inches off the floor on either side of the door and are applied for your safety. 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.
