40-189 for heavy door

A quick learner from New York, NY says:

I am looking of this item that may be able to handle a very heavy door. Even if I need two to use. But I need it to be rated for at least 300lbs if possible. Is there an industrial version o this?

You might need to use one of the commercial door closers like our 79-252, 79-253 or 79-254. The 40-189 are normally used for a residential type doors of average weight. Installing two or possibly three on the door might work, but since its not made for such weight there's no way to be sure.
