Retractable Lightweight Garage Door Gear
Availability:
Out of StockRetractable garage door gear lifting mechanisms are ideal for people who are making their own door or to replace the existing lifting mechanism on an old door where there are obsolete parts. The lightweight retractable garage door gear is designed to lift doors up to 45kg (approx. 100lbs) and up to 9'0" wide.
This particular garage door mechanism will suit many single width steel or aluminium door panels, and some lightweight timber panels. However, it's important to get the correct weight for the door panel in question to ensure compatibility.
To get an accurate weight for your garage door panel, you can disconnect it from the link arms, and carefully lower it onto a set of household scales under each bottom corner of the door. Combining the two will give you the weight of the door.
If you garage door panel is heavier than 45kg, then you will need a more heavy duty mechanism.
All gears have multi-position springs location to give great flexibility and improved door balance.
The gear packs are for Metal / GRP / Timber Garage doors.
- Special short arm: 5'8" to 6'4"
- Short Arm Door height: 6'0" to 6'7"
- Standard Arm Door height: 6'8" to 7'5"
Retractable gears are ideal for use with automatic electric operation. Fixing plates are recommended for steel, aluminium and GRP garage door to provide a suitable fixing for the door arms.
Note: Although a confident D.I.Y person should be able to carry out this work we recommend that you engage the services of a specialist installer.
This door gear has been designed for quick and easy installation. Through careful design it is possible to adjust the door after installation for very smooth operation. To obtain these benefits read the instructions RIGHT through BEFORE installation.
Caution: ALWAYS raise and prop the door in the open position before fitting, adjusting or removing the springs.
All instructions are given from within the garage.
