Tracks are for rollup or torsion spring doors- tilters and floders use pivots counterbalanced by tension springs.

You have the door up, you arrange a rope each side taking the load each spring holds and you use a pulley at each rope so you can safely raise and lower the door and hold it anywhere you want with the ropes.

With the door secured by ropes you can now remove the redundant and relaxed springs. Usually a clip, cotter or hitch pin pulled to remove a pin or link and then the spring hangs free. Not dangerous as long as there is no load on the springs as they store no potential energy.

Nope, My garage door is on tracks and uses tension springs.

That must be a really old way of doing it.

I've replaced several of these with the type you wind across the header and they still had tracks and rollers down the sides.

Roll up doors can use either type of spring, newer roll up doors which weigh more typically have torsion springs as they last longer and are considered safer during use, though more dangerous to instal.

I Have an original 1972 wood roll up with tension springs.
