Avalon's housing gives a quote nothing to assume from. The census puts the middle of its 1,854 homes at 1954, seventy-two years in, though it prints a margin of nineteen years on that median, so even the middle of the record is a soft figure. 81.3% of the stock was finished before 1980, and the table still will not settle into one era: 752 units date from 1939 or earlier, 468 from the 1970s, and the published margins on those two counts overlap, so there is no decade to load a truck against and no kit that covers a day of calls. The counterbalance is where the measuring starts, because it carries the weight and sets what the rest of the job has to match. Where a door lifts on extension springs, what gets priced is a system rather than a spring. DASMA's definition of one names three parts before a restraint is even mentioned — the spring that gets stretched, the pulleys it works through, the lift cables attached to them — and ANSI/DASMA 103 then requires the restraint, because a counterbalance spring or weight has to be held. On extension springs the thing that holds it is a containment cable, run down inside the spring to retain it if it breaks. That standard also asks that parts under tension resist casual removal, and it takes any one of three answers: hardware that cannot be pulled before the tension is released, fasteners needing a special tool, or red fasteners carrying ANSI Z535 warning decals. Red is one of the three, so a door with none of it has told you nothing either way. And all of it describes how a door system is built rather than what is over this driveway, so which of those three answers a particular door gives is settled by standing underneath it.
