The LiftMaster Formula I belt drive operator is quiet
as a whisper and tough as a steel-belted tire. The high-strength polyurethane
belt is reinforced with sturdy, flexible steel cords that resist the flexing
and tensioning of day-in, day-out opener cycling.
LiftMaster's 1/2 HP belt drive opener includes Security+® rolling
code technology. Each time the remote is activated, Security+ automatically
rolls the code over to any one of 100-billion new codes, never to be repeated. Liftmaster's
patented PosiLock technology ensures that once your garage door goes down,
it is securely locked and an intruder cannot gain entry by forcing your
garage door open.
For safe operation, LiftMaster belt drive models are equipped
with the Protector System®, which projects an invisible light
beam across the inside of the garage door opening. If anything interrupts
the beam while the door is going down, the door automatically reverses
before making contact.
These operators come with a lifetime motor and belt warranty, a wide
variety of optional attachments and features, and are a great choice if
your garage is located below living space due to their quiet operation. |
