Liftmaster Screw Drive OpenersLiftmaster screw drive
garage door openers are as durable and strong as the more
historically and commonly used chain drive systems with
the added benefit of producing less noise and being more
reliable. The reliability comes from the screw drive
mechanism itself, which is a screw that turns while
connected to a threaded rod that moves the door to open
or close. The screw and rod system are a simpler design
than chain drive systems and with fewer moving parts.
With fewer moving parts the Liftmaster screw drive opener is
more reliable than a chain drive system because there are fewer
parts to wear against each other as the opener operates. Fewer
parts also allow for more strength to be directly delivered to
the handling of the door as the power of the motor is not
diminished as it moves through unnecessary mechanisms.
The screw drive
systems also offer a smooth and steady opening process.
Where a chain drive system can pull and tug during
operation, the screw and rod mechanism do not allow for an
uneven process thus reducing wear on the opener and the
garage door itself.
Liftmaster offers two models of screw drive opener. The
first is the Premium Series 3240 which uses a 1/2 hp motor to
quietly and reliably operate in either a hot or cold climate.
The Contractor Series 3130 is a 1/3 hp motor driven screw drive
opener that is also built for extreme climates and can perform
well with a steady open or close process.
Liftmaster Premium Series screw drive openers also include
access to the same list of available options and accessories
that can give the opener system the custom features that can
make any particular system unique to each customer. Liftmaster
