Dormakaba Commercial Hdwe QDC115-689 Door Closer

Product Description

The DORMAKABA COMMERCIAL HDWE QDC115-689 is an extra heavy duty EDA door closer finished in aluminum, designed for commercial door applications where reliable, controlled latching is required. Measuring 13.8 inches in length, 7.9 inches in width, and 6.1 inches in height, this unit is built to handle the demands of high-traffic commercial entrances. It is typically installed by commercial door hardware technicians or licensed contractors working on institutional, retail, or office building projects where code-compliant door closer performance is required.

This door closer is suited for commercial installations requiring extra heavy duty performance, such as main entry doors, corridor doors, and high-use interior or exterior openings. The aluminum finish integrates cleanly with standard commercial door and frame finishes. It is sold as a single unit and is appropriate for new construction as well as retrofit replacement projects where an upgrade from a standard-duty closer is needed.
