The synoris 800 garage door opener comes with an 800 Newton motor (equal to 1 HP) and is especially suited for heavier garage doors. This powerful motor is attached directly to the door and glides silently along a stationary chain which is embedded in a sturdy steel rail. This design results in less stress on the gear and motor throughout its working life.
The synoris 550 garage door opener comes with an 550 Newton motor (equal to 3/4 HP). Unlike conventional garage door opener that use a noisy chain, belt or screw the synoris has only one moving part with no moving chain or belt. Perfect for homes with living spaces above or next to the garage.
