Garage Door Torsion Springs - IPPT

Torsion spring inch per pound turn" (often abbreviated as "IPPT" or "in-lb/turn") is a measurement used to quantify the torque or rotational force required to wind or unwind a torsion spring by one turn.

In the context of garage doors, this measurement is important for determining the appropriate size and strength of the torsion spring needed to effectively counterbalance the weight of the door. The IPPT rating helps garage door installers and manufacturers select the correct torsion spring for a particular door size and weight.

For example, a torsion spring with a higher IPPT rating can generate more torque per turn, allowing it to support heavier garage doors. Conversely, a lower IPPT rating indicates a spring with less torque per turn, suitable for lighter doors.

When selecting or replacing torsion springs for a garage door system, it's crucial to match the IPPT rating to the specific requirements of the door to ensure safe and efficient operation.
