0.151X49.70 | TorqueMaster Original Spring | TM/TM1

When replacing TorqueMaster Springs it is necessary to identify if the door utilizes the original TorqueMaster One, or the newer TorqueMaster Plus spring system.

The easiest way to distinguish these is by visually inspecting the end brackets. ToqueMaster One has a counter and winding fitting to the end, while TorqueMaster Plus has the anti-drop pawl and rachet gear inside the end bracket. You can also determine each type of spring system by looking at the winding shaft on the end of the springs.

The counterbalance weight (e.g. Wt. or Wgt.) on the sticker is the most important when determining the correct spring needed.

The spring's job is to store the mechanical energy from the weight of the door.  When this is done correctly the Opener | Operator has to do minimal work. It is best practice to choose springs within 10 pounds of the garage door weight as outside that will cause the motor to work harder than needed to open/close the garage door.
