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.
