Springs, cable, ball-bearing rollers
We carry standard torsion springs in the wind sizes that fit that era, along with the galvanized cable and ball-bearing rollers that wear out on a 40-plus-year-old door well before the panel itself gives up. We also stock opener logic boards and drive gears for the chain and belt units that replaced the original cantilever units sometime in the 80s and 90s, since a lot of Caledonia garages went through one opener swap already.
