Complete Head unit only for replacement of LCO75 garage door operator Does not include rails or Chain or drive gear
The Model LCO75 3/4 HP Deluxe Dual Lamp Garage Door Operator is Linear's most powerful door operator yet. It can be used in light-duty commercial installations or in residential applications with heavy carriage house style garage doors. The LCO75 has a maximum duty cycle rating of 13 operations per hour; 50 operations per day, far more than other operator designs.
The LCO75 can be used with Linear's belt-drive or chain-drive rail systems Rails not included with this Head Unit
To make installation even easier, all the controls and indicators are on one side of the operator. Easy access is provided for the open and close limits, open and close door force settings, transmitter learn/erase button, and RF signal/interference indicator. The built-in diagnostic system flashes the operator's dual courtesy lights to indicate six possible trouble conditions.
The LCO75 includes infrared safety beams, a 3-button Model MCT-3 transmitter, a lighted deluxe wall station with vacation mode radio disable switch and courtesy light control button.
