QUESTION: how do these install in the track ? by None N 4/28/2014
ANSWER: I mounted them directly to the track, but used a piece of 1/4" steel plate to create a brace to avoid tearing the track. by Michael P a
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
REPLY: Mine didn't have bolts or instructions. You don't find this out until you receive them! by Dick R r
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
