For San Clemente calls we load for 1980s-era torsion setups first, since that's what the build year here points to - standard torsion springs in the common residential diameters, extension spring sets for the older side-mount configurations some of these houses still carry, and a run of steel rollers and hinges sized for single and double doors from that period. We also carry photo-eye sensor pairs and standard remote/wall-control units, since openers from that era have usually already been swapped once or twice and the replacement units vary in what they're compatible with. What we don't load as standard stock: specialty custom panel sizes or glass-insert sections, since those are order items once we've measured the door in person. If your door needs one of those, the first visit is a measure-and-quote, not a same-visit fix - that's the honest limitation, not every job closes in one trip.
