Description
The International Door Closers 231A is a concealed overhead door closer designed for center-hung aluminum doors and frames ranging from 31 to 41 inches wide. Built-in positive back stop and centering mechanism hold doors firmly closed against wind and draft while enabling smooth, controlled closing and latching speeds via two independent valves.
This closer installs within aluminum headers or transom bars as compact as 1-3/4" x 4", making it ideal for retrofit and new construction projects. The "A" type arm assembly and 105-degree back stop provide reliable performance on standard commercial aluminum door systems.
