Description
The International Door Closers 233A is a concealed overhead door closer engineered for center-hung aluminum doors and frames sized 31" to 41". It solves the problem of uncontrolled door swing and wind draft with a built-in positive back stop and centering mechanism that holds doors securely closed while allowing smooth, controlled closing action.
This closer fits standard aluminum headers or transom bars as small as 1-3/4" x 4" and features two independently adjustable speed control valves for closing and latching. Since it is non-hold-open, it suits standard entry and passage door applications. Contact E.D. Locks & Security at sales@edlocks.com or 1-877-207-6067 for expert guidance on sizing, installation, and keying to ensure proper fit and performance.
