Headroom targets follow the requested radius + 1″ rule: 13″ for 12″ radius and 16″ for 15″ radius. The track route is diagrammatic; actual mounting offsets and spring/operator clearances depend on the selected system. Sections are restricted to nominal 18″, 21″ or 24″ heights. Confirm availability for the selected door model.

Automatic strut counts use the published standard, non-wind-rated table. Conflicting LI3000 / CC4000 requirements at 12–14 ft remain subject to order confirmation. Lincoln 3000 uses the starred model entries. The Lincoln 1000/2000 table lists only widths 16′-2″–20′; narrower widths and section counts other than four or five require an order schedule. Vista uses ClearView aluminum reinforcement; the manual’s width-based quantity note names model 3552, so VI1000 totals require confirmation. Wind-rated orders use their engineered drawing. H1 lists the requested nylon rollers and 14-gauge hardware. Steel doors list galvanized end stiles; Vista retains its aluminum frame specification.
