Comments / Questions

COMMENT: I have a Liftmaster 8500 door opener which relies on gravity to lower the door. If the door is completely raised up, gravity alone won't work and the cable may come off its spool. These springs will push the door down so that gravity can take over and prevent a catastrophe. by Gerd K 11/29/2014
COMMENT: In cold weather my jackshaft open doors have an issue if they are allowed to go up all the way . They don't want to come down on there own as the cable tensioner sense's a loose cable and stops it . I don't want to lower the opening height so this is the best option . by Chad S 11/22/2014
QUESTION: how do these install in the track ? by None N 4/28/2014
ANSWER: I mounted them to pre-drilled angle iron like used for mounting the rear of the tracks. Used the existing vertical run and added another vertical run for the front mounting slot. Have no idea if this is correct as there were no instructions but it works well. by allen m a
ANSWER: You may have to drill your own holes- I did. I mounted it on the top side of the track with two 3/8 bolts if I remember right. This lined the plunger up with the end of the door. I only ended up using one, I figure ill find a use for the other some day soon! This is a great product- works better than the "leaf spring" style returns that are also available because this has almost a foot of travel that it pushes back. Good luck! by Russell G a

QUESTION: do i need 2 for 1 door? by None N 11/11/2012
ANSWER: Yes, one spring on each side of the door. One per track. Are they sold in pairs I don't think so. If I recall correctly, I ordered 4 springs for two doors. by E R a
