Janus 1-5/16 " Cam Action Spring Tensioner

The Janus Cam Action Ratchet Spring Tensioner Assembly is designed for professional installers who need controlled, balanced spring adjustment from a single point. Mounted on one end of the door axle, this assembly allows both garage door springs to be tensioned equally and simultaneously, reducing setup time and improving adjustment accuracy.
