Most garages in Sun Lakes were built right around 1990, which puts the doors squarely in the steel sectional era - two-inch galvanized track, nylon or steel rollers, and either a single wide door or a smaller single-car door depending on the layout. These aren't the thin aluminum doors from the 1970s or the insulated composite doors going up today; they're a specific middle generation, and the track profile and roller stem size matter when a door jumps its track. We carry the roller and track hardware that matches this era on the truck, along with the hinges and cable drums that tend to go along with it, so a visit usually doesn't turn into a second trip waiting on a part. What we don't always have on hand is a replacement track section for an unusual door width - if your opening is nonstandard, we may need to order that piece, and we'll tell you before we start, not after.</br>That's the honest limit: we stock what fits most of what's out there, not every custom size.</br>
