Description
Glynn-Johnson 450 Series Hold-Open Medium Duty Surface-Mounted Overhead Door Holder is for single acting doors – interior.
The best door control device is one that operates overhead, with an arm functioning from the jamb to the top of the door. When the door stopping or hold-open does not exceed 110°, this device is by far the most efficient.
