When I built my barn, I originally ordered a 12x10 ideal "clopay" door, 2 inch thick, r16.7 etc etc. I decided I wanted a 12x12 instead and figured I could just order 1 more panel, extend the track and wind the springs a little tighter. Well I've now found out that I was far off on that assumption. I did find a local garage door company that got in contact with clopay for me to find out what springs I did need for the 12x12. The company let me bring my track and springs meant for a 12x10 and exchange them for the track and springs I now needed. Anyways I got the door all up, and the directions said to wind the springs 12.3 turns,once I got to 10 turns the door started to lift itself. So I backed the spring off to 8.25 turns and that was just enough that it wouldn't lift up by itself,but now once I lift the door over 6 foot it's out of spring and becomes very heavy. The horizontal track is mounted perfect and the door is not binding in it. The red spring is on the left and black is on right,and I wound them both upwards. The only thing I can figure is I have to heavy of springs and need springs that will allow me to turn them 12 turns without the door lifting. I got back in contact with the garage door company that sold me the springs and Im not having much luck, there basically claiming install error. I also installed a 10x10 high lift door and it's working flawlessly. The spring dimensions for the 12x12 are 1 - 2" ID 262 WIRE 50" LONG AND 1 - 2" ID 250 WIRE 45" Long. Basically I'm trying to figure out what springs I actually need to make this sucker right so I can move onto the next project. Sorry for the long read
