Features

Can be used for either parallel arm or top jamb applications. Unitrol arms combine the features of a double lever arm overhead door stop/holder with the backcheck feature of the door closer to reduce door stopping shock loads to a minimum. The Unitrol uses a compression spring buffer at the soffit plate/arm shoe that will absorb 30 lbs. offorce, 5° prior to the doors dead stop. Coupled with thedoor closers backcheck feature, this arm provides the most controlled stop available with a surface door closer.
