Attached garage door stock
That's the stock you'll find whether you're in Manchaca, out past Creedmoor, or up toward Sunset Valley and Bee Cave - attached two- and three-car garages, steel sectional doors, torsion springs mounted on a center bracket rather than the older side-mount style. It's a more uniform build era than you'd find in an old downtown core, which means parts availability is generally decent: openers and springs from this period aren't hard to source.
