Safety Tips for Garage Door Replacement
Panel configuration
Scrape off any sealant left by the old door sill trim first and measure the new doorstop. Most trim comes with a vinyl weatherstrip insert. Cut the new fence to the desired length and lift it into place. Nail the new stop molding to the header. Install the two vertical rails at the same height. Set one track, then measure your position to place the other. Install the horizontal rails over the vertical rails. Screw each angle bracket to the jamb frame holding the trim edge back about 1/8 in. From the edge of the opening. This will allow the trim strip to press firmly against the door. Finish by installing the vertical trim, keeping them about 1/4 inch off the ground.

For the door to function properly, the panels must be installed level. Center the first panel in the opening and check it with a 4-foot pipe. level. If it leans even a little bit, wedge the low side until it is correct. Next, drive a nail into each side of the door frame and bend the nails over the ends of the panel to keep it upright. Place the second panel on top of the first and secure it in a similar manner. When you have attached the third panel, recheck the level and adjust the shims if necessary. Finally, attach and secure the top panel.
Hardware installation
Starting at the bottom, install the hinges and brackets to join the panels. The hinges and brackets on the edges of the door also support the rollers. After all brackets and hinges are installed, screw the strut through the top panel. This reinforcement provides wind resistance.
Before installing the vertical rails, slide a roller onto each edge and bracket hinge. Next, screw the rail brackets to the door frame. Raise the rail 1/2 in. Placing it on a wedge and screw the rail in place. Measure from the top of the track to the center of the first roller. Install the vertical rail on the opposite side of the door, making sure its top is the same distance from your first roller. The next step is to install the horizontal guides. Each horizontal track has a 90-degree curve that meets the vertical track. The curve is supported by an angle of support. Screw this bracket to the door jamb and move along the horizontal rail to the hanger bracket. Our hanger brackets were already in place, but if you’re starting from scratch, install the brackets so the rails are level and parallel. With the hanger in place, screw in the rail.
Next, assemble the torsion bar components. Slide the springs onto the rod from each direction, followed by the cable drums. Look for a paint splatter on one of the springs to determine the correct orientation for both springs on the bar.
Raise the bar on the horizontal rail supports and install the end bearings. Each bearing bracket will bolt directly to the top of the angle bracket of a horizontal rail. Next, level the center of the bar and install the center bracket. In addition to supporting the rod, this bracket locks the stationary ends of the springs together. Finish by routing the cables from the bottom panel brackets to the cable drums on the torsion bar. With the components assembled, it’s time to wind the springs. This is a critical step because only the correct amount of tension will do. If you miss your mark, your door will not stay open or it won’t stay closed. Start by placing locking pliers on the track to prevent the door from moving as you work. Then paint a stripe along with each spring so you know how many full turns you have made. Doors this size may require seven to eight complete turns; see instructions. In either case, insert the winding rods and carefully tighten each spring. Finish the job by reconnecting the garage door opener.
