Chamberlain PD610D Power Drive 1/2-HP Chain Drive Garage Access System
The Chamberlain PD610D Power Drive 1/2-HP Chain Drive garage door opener delivers exceptional, all-around performance. Its durable 1/2-HP motor is combined with an industrial-strength chain drive to provide smooth, steady performance and lifting power year after year. The Protector System safety sensors with Rapid-Snap brackets project an invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down.
