DoorMathPro, a garage-door spring calculator for the truck and the job site
An offline calculator suite for garage-door technicians that sizes springs, matches replacement stock, estimates door weight, and produces printable job specifications.
Field notes
The suite takes field measurements such as wire size, spring length, inside diameter, door dimensions, drum model, and high-lift distance, then displays IPPT, cycle, and replacement-stock results. Its matcher compares alternatives across wire gauges and IDs, while the spec-sheet workflow adds torque checks and a customer balance sign-off. The page lists support for more than 30 factory models and describes camera-based identification and AI assistance as available features, though their operation is not independently demonstrated in the extract.
