The spring is 9 1 2 not counting the loops which are 3 4 each the diameter is 3 4 and there are 72 coils.
Attic door spring broke.
In order to get the door to close we have to bend the arm back in as much as we can and hook the spring back over the bracket at the top.
The door usually is counterbalanced to the ceiling with folding steel arms and two heavy duty springs.
If an attic light is not installed carry a flashlight into the attic.
The arm on that side looks like it s bent out.
There are 3 hooks so the spring can be pulled to the best one.
Ask the assistant to lift the steps and close the stairs.
On one side the spring always comes off its bracket when the door opens.
An attic stair which is actually more of a ladder is a fairly simple apparatus consisting of a folding series of steps attached to a door.
It s similar to the one shown.
Pull down the stairs and switch on the attic light.
If the springs are worn rusted loose or broken the integrity of the entire device is seriously compromised and an immediate repair is necessary.
