We stock galvanized lift cable in the standard gauges used on residential doors, along with the clips and drum hardware that fit the bracket styles common on homes built through the late 1980s and into the 1990s. For Milford specifically, that covers the bulk of what we run into - the door is old enough to need real parts, not so old that it's running obsolete hardware nobody makes anymore.
What we don't carry on the truck is anything custom - oversized commercial cable, non-standard drum diameters, or hardware for doors that have been modified from stock. Given this area's income profile, most homeowners here are running standard residential doors rather than custom installs, so this is rarely an issue in practice, but it's worth saying so nobody assumes we show up with every size imaginable.
