My stop switch is a couple inches from the head unit. The builder originally had it further down the track, which left the door a few inches down into the opening. Looking up the driveway, that doesn’t look so clean and it was closer to my pickup roof than I cared for. I just got up there and experimented. I figured, if it doesn’t work, I’ll put it back. The springs are only needed to assist on the vertical, to get the door started upward. Once the panels start going horizontal, the opener can handle the weight. You just need to make sure if you have tension springs and the springs go slack from the new adjustment, they can’t get caught on anything or come unhooked. My doors all have torsion springs, so NBD.
I see a lot of those on tiny homes and RV owners are starting to adopt them, as they have way more BTU potential, especially in the summertime when window blinds and multiple roof units can’t get the job done.
