Replacements

Current models named as replacements by the manufacturer, or with similar published specifications.

Replacement suggestions compare published specifications. They do not guarantee fit or compatibility. Check the motor head, crown and drive adapters, brackets, wiring and remote pairing with the manufacturer or a qualified installer before ordering. Mains-powered motors must be connected by a qualified electrician.

Same brand, equivalent specification

Current models of the same brand, from another series, whose published values pass the tolerance table.

OpenAxia comparison of published specifications — not a manufacturer statement

Match with changesWithin the hard tolerances, but at least one difference has a consequence, such as new remotes or a different way of setting limits. Each difference is listed.
