Commercial
sites have needs that are very different from residential
applications, frequency of use being the most common
difference. Whereas the typical garage door opener
may only be used a few times daily, a commercial operator
may be used several times an hour. With
this heavy industrial usage in mind, LiftMaster® has
developed a full
line of operators that provide the highest levels of strength and
durability. LiftMaster professionals can assess precisely what you
need and install a reliable system your business can count on for
many years to come.by LIFTMASTER
