Installing a new sectional door

Before beginning to install your new door, it is critical to read and understand the fitting instructions. Getting any queries answered before beginning can save you time in the long run.

You can begin once you are familiar with the fitting requirements for your specific sectional garage door.

1. Assemble the door frame and fasten it into place, making sure it’s square and level in the opening with packers as needed.
2. Drill the needed fixing holes with a suitable masonry drill, such as an SDS drill or similar, and insert the supplied plugs. When finished, use a cordless drill with a socketed attachment or a socket set to secure the supplied fasteners / washers.
3. Once the frame’s fixings are complete, recheck to ensure the frame is still level and square before proceeding to fitting the tracks. Follow the fitting instructions, which will require connecting the tracks to the tracks on the frame, ensuring the joints are smooth, and then hanging the tracks from the ceiling joists or side walls. Before attaching the tracks, measure their diagonals to ensure they are square.
4. Install the springs. Depending on the gear configuration of the sectional door you purchased, you may need to install a spring at the back of the tracks, springs down the sides of the frame, or overhead springs on the frame. Follow the manufacturer’s recommendations and use extreme caution when handling garage door springs.
5. After the springs/cables are in place, insert the rubber strip into the channel on the bottom door panel. Spray the channels with WD40 or something similar to ensure the rubber slides in properly. Once this is completed, the panel can be installed.
6. Position the panel and clamp it to the frame to prevent it from falling while you attach the brackets and wheels. After you’ve installed all of the brackets and wheels, you’ll be able to attach the spring cables, if your door has this type of hardware.
7. Continue to install the remaining panels, making sure the BRACKETS AND WHEELS are properly installed otherwise the door will not open properly!
8. After you have all of the panels in place, you will need to tension the springs. Use caution and WEAR STRONG GLOVES if you have any problems with the tensioning. Sectional garage door springs are extremely powerful when tensioned, and if you are not careful, they can inflict SERIOUS HARM to your hands.
9. Lubricate the tracks and moving parts, and install the locking handle if the door is manually controlled.
10. If the door is to be operated by a garage door opener, install it according to the manufacturer’s directions, making sure the boom is level and centrally fastened to the door.
