For doors from Heathrow's era - built around 1998 and later - we carry standard galvanized aircraft cable in the common lift lengths and gauges used on torsion-spring residential doors. That covers the bulk of calls here without a special order. We also carry the matched drum cable clips and safety cable for doors where the original hardware is still in reasonable shape and just needs the worn cable swapped out.
What we don't carry on the truck is anything custom-length or for a door style that's uncommon in this market - oversized commercial doors, older wood doors with non-standard track spacing, or anything requiring a manufacturer-specific drum. If a job needs one of those, we'll tell you upfront that it's a special-order part and give you a realistic timeline rather than guess.
Because most Heathrow doors are newer than the older stock found elsewhere in the Sanford service area, we're not usually digging through odd sizes trying to match a drum that hasn't been manufactured in decades. That's a real advantage on this side of the territory: the hardware is more standardized, so the repair tends to move faster once we're on site, not because we work faster here, but because the parts match is simpler.
