Commercial Door Operator Systems

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.

Effective August 29, 2010, Underwriters Laboratories will require all commercial door operators manufactured on or after this date to be fully compliant to UL325-2010, the standard to which commercial door operators must comply in order to achieve UL approval and bear the UL325 mark.
