A door built around 2000 is almost always a steel sectional, insulated or not, hung on standard torsion springs sized for a 16-foot double or an 8 or 9-foot single - builder-grade hardware, not the custom stuff you find on older, one-off doors. We carry standard-wind torsion springs in the common cable and drum sizes, nylon and steel rollers, and the extension spring brackets some of these builder installs still use on single-car doors. What we don't carry on the truck is obsolete wood panel hardware or odd European track systems - those aren't common in a neighborhood built this century, and if one shows up, we order the part rather than fake a fix.
