For a 1992-era door in this area, the truck carries standard torsion springs in the common wire sizes, extension springs, galvanized lift cable, nylon and steel rollers, and the hinges and end bearings that wear out on doors built to that decade's specs. Openers of that vintage are usually 1/2 horsepower chain or belt drive, and we stock drive gears and sprockets to match the common brands sold through that era. What we don't carry on the truck is anything discontinued or proprietary - some builder-grade openers from the '90s used parts that manufacturers stopped making years ago, and if that's what's on your wall, we'll tell you straight whether it's worth chasing a part or worth replacing the unit. That's the one honest limit here: we're not going to pretend a fifteen-year-old part is sitting in a warehouse somewhere waiting for your call.
