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 series, current models

Current models of the same series whose published values pass the tolerance table.
