We carry torsion springs sized for both the older 8-foot single doors common across the rest of the service area and the 16-foot double doors that dominate Harvest's newer stock, along with standard steel rollers, cables, and the hinges that fit flush-panel doors from the 2000s. What we don't keep on the truck is anything specialty - glass-panel inserts, custom wood overlays, or opener boards for a brand that's gone out of production. Those get ordered, and lead time runs on the supplier's schedule, not ours. If your door is one of the newer, heavier insulated models that's become more common as household incomes here have climbed, tell us the model number when you call; it saves a second trip.
