Norton 78B-D-PA 690 Door Closer

The Norton Series 78-B/F Traditional Surface Closers represent a combination of traditional styling and modern closer features. All closer sizes are contained within a single size aluminum alloy shell. These closers have an unusual ability to accommodate power adjustment to their environment. The adjustable clock coil spring provides a small incremental increase or decrease through a wide range of closer power. They can be adjusted to meet the exact power requirements of the installation. Sweep speed, latch speed and backcheck cushioning can also be adjusted to door, frame and variable conditions.
