The All-O-Matic SL-90dc is newly redesigned, and has had more features added onto this operator. Some of these features include a standard mechanical foot pedal and larger gearbox with internal disconnect for a higher gate capacity. Brushless DC motors are smooth and quiet but are powerful and durable and require zero maintenance. The built-in battery backup offers up to two weeks of uninterrupted operation in the event of a power outage.
