The Janus 1-5/16 inch cam action ratchet spring tensioner assembly is designed to provide precise and controlled adjustment of rolling steel garage door springs. Compatible with 1-5/16 inch diameter axles, this tensioner allows both springs to be adjusted evenly and simultaneously from a single point on the door axle. Featuring a cam action, spring-loaded design, the tensioner delivers fine tuning in 1/8 turn increments for accurate spring loading.
