This overhead commercial door closer replaces the original “Kawneer Husky” concealed overhead closer.
The new version features a two-speed closing control to prevent the door from slamming on single-acting applications.
It also prevents over-swing on double-acting applications.
This closer is ideal for schools, office buildings, hospitals and department stores.

NOTE: Through the first 80 degrees of the closing cycle, the door should be kept at a moderate speed to prevent “heel bumping” as someone enters through an out-swing door.
