This is the electric opener which operates this door. I'm picturing it here because you pull the rope to disconnect the trolley, run the trolley under power to the fully-open position, and then disconnect power before working on the door. Then you should lock the door down with either the security lock or with Vise-Grips or C-clamps. This avoids the door lifting when you don't expect it as you are applying spring adjustments. It you were to foolishly overwind the spring without the door locked down, you could possibly find the door trying to leap up to the raised position when you aren't prepared. That would likely knock your grip off the winding rods, with potentially disastrous results. I like to work under the safety principle that serious accidents should be physically possible only when you make two or more stupid mistakes at the same time.

Adding a new garage door provides a dramatic difference in your home’s appearance.

You can choose from three basic types of steel door: (1) steel only; (2) steel with insulation on the inside; and (3) steel on both sides with 1-3/8 to 2 in. of insulation. Other features that add to the cost are thicker insulation and windows, especially insulated windows. The do-it-yourself tensioning systems also add a little to the door’s cost. Be sure to specify exactly what you want.

Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.
