We offer a full line of commercial garage door openers to fit the needs of the customer. For smaller commercial sectional garage doors we recommend using the Liftmaster 8900W these operators are rated for 14 feet maximum height and 300lbs total weight. For rolling steel doors we recommend the 8950W for doors up to 12 feet maximum height and maximum weight of 850lbs.
For large sectional commercial doors we recommend the Liftmaster J or H. These are equipped with MyQ for automated opener control and are equipped with a soft start/stop feature.
The Liftmaster J, jackshaft opener is available in ⅓, ½, ¾ and 1 horse power. The horse power needed is based on the total square footage of the sectional door it will be installed on.
The liftmaster H, hoist opener is available in ⅓, ½, ¾ and 1 horse power. The horse power needed is based on the total square footage of the sectional door it will be installed on.
The Liftmaster MJ is another option, but it does have some limitations that should be considered. The MJ is not MyQ ready so it can not be controlled through a cell phone, tablet or computer. The Mj is not equipped with the soft start/stop feature which can create problems in the future. These problems include chain stretch because when activated in open or close mode the motor is pushing or pulling with full force throughout the cycle. This can cause premature chain stretch and it can bend the spring bar and damage the sprocket over the course of normal use.
There are other options for larger commercial doors like the Liftmaster ATS. The ATS is a commercial opener that is ceiling mounted and utilizes a rail system, but can only be used on standard lift sectional doors. The ATS is a light duty commercial opener.
For commercial sectional doors that are high lift or full vertical, a jackshaft or hoist type door opener must be used, a ceiling mounted opener with a rail will not work for high lift or full vertical doors.
There are other commercial opener options, but this information will point you in the proper direction for the type of opener you will need. When considering commercial openers for your sectional door, it is important to estimate the number of times the door is opened and closed throughout the day and then you can better select the opener that will best fit your commercial door opener needs. Commercial openers are rated for a certain number of open and close cycles per day so it is important that this is at least considered when selecting the proper opener.
