The technology of a traveling motor that attaches directly to the garage door was invented by SOMMER in 1986.
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.
The motor glides silently along the stationary chain that is embedded in a sturdy steel rail, creating the quietest garage door opener available.
The spring-loaded chain will never sag down.
The sensitive internal obstacle detection and the safety sensors constantly monitor every door movement and ensures the highest level of safety.
Direct Drive technology requires no maintenance and makes this garage door opener extremely durable and long lasting.
The SOMMER garage door opener is Strong and Durable like a chain drive and quieter than a belt drive brought together in one state of the art design.
