We carry torsion springs sized for the weight range common to 1960s and 70s door construction, since that's what most of this pocket of the service area still runs, plus the drums and cables that pair with them. We stock standard travel cables and rollers that fit the older track gauges still on a lot of these houses, not just the newer roll-formed track that's become standard on recent installs. Openers are the one item we don't guess on - if yours is original or close to it, we'll tell you what we have on hand versus what needs a return trip, because opener models and their logic boards vary more than spring stock does. Given the cold-climate wear this area sees, we default to galvanized hardware over painted steel when a part needs full replacement, since it holds up longer against the freeze-thaw cycling that wears out unprotected steel faster here than in milder regions.
