The SilencioTM operator is a low headroom apartment type garage door operator designed for use on industrial standard lift sectional doors with high cycling daily frequency requirements.

The operator incorporates a drum-shoe type solenoid brake, low vibration braking system, as well as other integrated enhancement features which reduce noise emissions by a magnitude of 4*.

The operator is available with the new Electronic Control Board (BOARD 070) with or without the option of electrical control for MONITORED external entrapment protection devices (UL325-2010 compliant).
