Dormakaba Commercial Hdwe QDC211F-689 Grade 1 Door Closer

Product Description

The DORMAKABA COMMERCIAL HDWE QDC211F-689 is a Grade 1 door closer designed for commercial door applications requiring reliable, controlled closing performance. Supplied with a tri-pack arm configuration and a full cover in an aluminum (689) finish, this unit provides installation flexibility to suit a range of door and frame conditions. At 6.3 pounds and measuring 13.4 inches in length, 5 inches in width, and 3.2 inches in height, it is built to the dimensional standards expected in heavy- and standard-duty commercial openings. Licensed door hardware installers and commercial contractors are the primary trades that specify and install this product.

This door closer is intended for commercial interior and exterior door openings where Grade 1 performance and a coordinated aluminum finish are required. The tri-pack arm allows the installer to select the appropriate arm style for the specific door hand and application condition on site, reducing the need to pre-specify arm configuration at the time of ordering. Typical installations include office buildings, retail spaces, schools, and other commercial facilities where consistent door control is a code or specification requirement.

Installation Notes

Installation is performed by licensed door hardware technicians or commercial contractors familiar with ADA door-force requirements and applicable building codes. Power to any adjacent access control or electrified hardware should be disconnected before beginning work on the door assembly. Proper arm selection from the tri-pack should be confirmed against the door hand and swing direction before drilling or fastening. Follow the manufacturer's template and torque guidance for fastener installation into the door or frame.
