* Inspect the Opening: Ensure the garage door opening is square and level. Measure the width, height, and side room to ensure they match the door’s specifications. Check for any obstructions or uneven surfaces.
* Prepare the Walls: Locate the wall studs around the opening using a stud finder. These studs will be used to mount the tracks. Reinforce any weak or damaged studs.
* Check for Utilities: Before drilling, check for any electrical wiring or plumbing behind the walls. Use a wire tracer or consult with a professional if necessary.
* Clear the Area: Remove any obstacles from the garage floor and the surrounding area. This will give you plenty of room to work.
* Inventory: Unpack all the components of the garage door kit and inventory them against the parts list in the instructions. This will ensure you have everything you need before you begin.

Step 2: Install the Horizontal Tracks

* Mark the Track Location: Use a measuring tape and level to mark the location of the horizontal tracks on the walls. The bottom of the track should be level with the top of the door opening. Account for the headroom required for the door to fully open.
* Attach the Vertical Tracks to the Walls: Secure the vertical tracks to the wall studs using lag screws. Ensure the tracks are plumb (perfectly vertical) and aligned with the marked locations. Use shims if necessary to level the tracks.
* Attach the Horizontal Tracks to the Vertical Tracks: Connect the horizontal tracks to the vertical tracks using bolts and nuts. Make sure the tracks are properly aligned and the connections are secure.
* Support the Tracks: Use angle iron or track supports to reinforce the horizontal tracks, especially if they are long or unsupported. Attach these supports to the ceiling joists.
* Level and Secure: Double-check that the tracks are level and plumb. Tighten all the bolts and screws to ensure a secure and stable installation.

Step 3: Assemble the Door Sections

* Lay Out the Sections: Place the door sections on a flat, clean surface. Protect the sections from scratches by placing cardboard or blankets underneath.
* Attach the Hinges: Attach the hinges to the door sections using screws. Follow the manufacturer’s instructions for hinge placement. Typically, hinges are installed along the top and bottom edges of each section.
* Install the Rollers: Insert the rollers into the hinge brackets. Ensure the rollers spin freely. Some rollers have sealed bearings and require no lubrication, while others may need occasional lubrication.
* Join the Sections: Carefully stack the door sections on top of each other, aligning the hinges. Insert bolts and nuts through the hinges to connect the sections. Tighten the bolts securely.
* Reinforce the Top Section (if required): Some garage door kits include a reinforcement strut for the top section. Install this strut according to the manufacturer’s instructions to prevent the top section from bending or warping.

Step 4: Install the Door

* Position the First Section: Carefully position the bottom door section in the garage door opening. Ensure it is centered and level. Use shims if necessary to level the section.
* Attach the Rollers to the Tracks: Insert the rollers of the bottom section into the vertical tracks. Ensure the rollers are properly seated in the tracks.
* Raise the Door Section: With the help of your assistants, carefully lift the bottom section into the tracks. Use a chain hoist or come-along if the section is too heavy to lift manually.
* Secure the Section: Clamp the section to the tracks to hold it in place while you install the next section.
* Repeat for Remaining Sections: Repeat the process for the remaining door sections, attaching the hinges, inserting the rollers, and lifting the sections into the tracks. Ensure each section is properly aligned and secured.
* Final Adjustments: Once all the sections are installed, check the alignment of the door. Make any necessary adjustments to ensure the door is level and moves smoothly in the tracks.

Step 5: Install the Spring System (Torsion Springs – Proceed with Extreme Caution)

Warning: Torsion springs are under extreme tension and can cause serious injury or death if handled improperly. If you are not comfortable with this step, please consult a professional.

* Mount the Header Bracket: Secure the header bracket to the wall above the garage door opening. Ensure the bracket is level and securely attached to the wall studs.
* Install the Torsion Tube: Slide the torsion tube through the header bracket. Ensure the tube is properly centered.
* Attach the Spring Anchor Bracket: Attach the spring anchor bracket to the torsion tube. This bracket will hold the torsion springs in place.
* Install the Torsion Springs: Carefully slide the torsion springs onto the torsion tube. Ensure the springs are properly oriented (left-wound and right-wound). Use the spring compression tools to wind the springs to the manufacturer’s recommended tension. *This is the most dangerous step. Follow the tool manufacturer’s instructions carefully.*
* Secure the Springs: Secure the springs to the spring anchor bracket using set screws. Ensure the set screws are properly tightened.
* Install the Cable Drums: Attach the cable drums to the ends of the torsion tube. Ensure the drums are properly aligned.
* Attach the Cables: Attach the cables to the cable drums. Run the cables down to the bottom of the door and attach them to the cable brackets. Ensure the cables are properly tensioned.
