Our experience is that you can find the right commercial door closures from Norton Door Controls. They have been designing and manufacturing door operating systems since 1880, and have a proven track record of innovation in developing new door operating systems.

This constant innovation and development is important to the person installing the door operating system and for the owner of the commercial facility where it will be in operation for years to come. In the first place it means years of reliable operation. But it also means that you will be able to find the right components for the job.

Norton Door Controls covers all the bases from simply preventing doors from slamming shut to full automated operation with energy saving features. These commercial door operating systems come in a wide variety of looks including a concealed system hidden in the door header.
