The TorqueMaster Plus / TM3 spring sleeve liner fits inside the metal torque tube and creates a protective layer between the torsion spring and the inside wall of the tube.

As the garage door opens and closes, the spring moves slightly inside the tube. The liner helps keep the spring from rubbing directly against the metal, which can reduce friction, scraping, and unwanted noise during operation. It also helps protect both the spring and the torque tube from unnecessary wear.

The sleeve liner also helps keep the spring supported and properly positioned inside the tube during installation and normal use.

This part is intended for compatible TorqueMaster Plus / TM3 garage door spring systems. When replacing a damaged or worn liner, check the required length and trim the replacement liner as needed to match your existing setup.
