QDC300 Series Standard Duty Door Closers
We engineered the QDC300 Series with the same high-performance materials and construction you expect from dormakaba, but in a smaller body. The smaller, narrower footprint of the QDC300 means you can put dormakaba quality on even the narrowest top rail doors. The QDC300 Series includes many premium design components standard, without costly upcharges. And with a wide range of available options and customizable features, the QDC300 provides flexible value without compromising quality.
The QDC300 is ANSI/BHMA Grade 1 certified, and significantly exceeds performance requirements. These closers are fully adjustable, with a barrier-free option to meet ADA requirements.
Strong materials and careful design ensures QDC300 closers perform reliably over the long term—and are backed by a lifetime warranty.
Installation and application
There’s no need to re-prep your door. The QDC300 has the same footprint as the Norton 1600 Series, so it’s quick and easy to retrofit. We engineered the QDC300 Series to be fully adjustable and usable on both interior and exterior doors. All-weather fluid, a variety of feature options, and non-handed and universal mount flexibility make it easy to stock and use the QDC300 in a wide variety of applications.
QDC300 closers are available for immediate shipment and are backed by lifetime mechanical and three-year finish warranties
