LiftMaster 3240 Premium Series 1/2 HP Screw Drive W/O Rail Assembly
The LiftMaster 3240 Premium Series 1/2 HP Screw Drive W/O Rail Assembly is easy to install and will have your opener running smoothly. This system is equipped with Motor Vibration Isolation System (MVIS®) to reduce noise and provide smooth operation year after year. This system also comes with the Protector System® which has safety sensors that project a light beam across the garage door opening and reverses automatically if something obstructs it. The patented PosiLock® system ensures the door remains securely locked when it is closed.
JOE –
GREAT TO USE THIS GARAGE DOOR OPENER WITH ALL THE LATEST IN BUILT SECURITY FEATURES. THE SCREW RAIL OF THIS OPENER DOES NOT NEED ANY LUBRICATION WHICH MAKES IT EVEN BETTER! WISH I HAD PURCHASED IT BEFORE.
nice product
