Because New Cumberland is served from Harrisburg, about 3 miles out, the truck carries parts sized for both the newer stock closer to the center of the service area and the older hardware common out here. That means torsion springs in a range of wire sizes, since original 1950s-era doors often don't match what's standard on new installs. Hinges and rollers in both the older oval-mount pattern and current styles ride along, along with cable sized for narrower original drums. We don't stock wood panel replacement doors on the truck - if a panel on an original door is split or rotted beyond patching, that's a special-order item, and we'll say so rather than pretend there's a quick fix in a toolbox. For straightforward spring, hinge, roller, and track adjustment work on hardware this age, the truck is set up to handle it in one visit.
