Customizing Roller Shutter Garage Doors
Roller shutter garage doors – Over the years, you can start to notice that your garage door seems to be heavier to open. Weather and paint change the weight of a door over time, which requires adjustments to the springs. Springs like on a drawbar have special procedures. Twist springs are dangerous because they are under extreme tension. Failure to wrap the springs correctly can cause serious damage to your garage.

Close the roller shutter garage doors completely and engage the garage door lock. Lock a pair of vice grips on the front of one side of the web above the other roll. Place a stairway ladder at the end of the torsion spring pointing towards the door groove. Lock a pair of vice grips around the top of the torsion rod, halfway between the cable drum and the spring with the handles of the vice grip resting on the wall. This keeps the cables tight on the drum when unloading spring. If you have two springs on the door you does not need to use a vice grip on the torsion bar?
Insert the end of a winding bar in one of the holes on the outer circumference of the spring lime cone. Hold the other end of the winding rod firmly and expect the downward force of pressure when loosening the spring setting screws. Turn the two adjusting screws on the winding cone counterclockwise with a 3/8 inch wrench. Slowly allows the winding road to rotate against the roller shutter garage doors from the pressure in the spring. Place the other wrap bar in your hand. Raise the first winding bar to rotate the spring until you can put the second winding bar in the next hole.
