Landing page captured for the 2026-09-08 issue.

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.
