Some questions about installing new garage door on old opener and other stuff
Hello all, love this place.
So I have a 1/2 hp older Craftsman garage door opener (see blurry pics, apparently I don't have steady hands) and I am hoping that I can purchase and install a newer metal door with the railing myself. I took a picture of the way it attaches to the door and it looks as though I could do it, but should I? I figure it has the juice to do it because I imagine the wood, watersoaked and all, weighs about the same if not more than a metal door would.
Would I be able to add an electric eye to the unit?
What is with those wires sticking out of the side of the unit? There's a white one, a red one, and a black one so I am assuming it is for some kind of light....
Should the pulley system be level? I noticed when I was taking the pictures that it is higher towards the garage door and sags towards the opener, leaving it a bit low to the ground anyways.
Any suggestions or bits of information would be appreciated too. Thanks!
