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. Signal Doors can assess precisely what you need and install a reliable system
your business can count on.  If you don't see what you are looking for click on the Liftmaster link on
