Glynn Johnson 103S32D Concealed Overhead Stop Size 3

Product Description

The GLYNN JOHNSON 103S32D is a heavy-duty concealed overhead stop designed for commercial and institutional door applications. Mounted inside the door frame head, this overhead stop controls door swing by limiting travel at a preset open position, preventing wall and frame damage without a floor-mounted device. The unit ships in a Satin Stainless Steel finish and is sized as a Size 3 stop, suited for heavier door assemblies. Sold individually, it is typically installed by commercial door hardware professionals or finish carpenters on interior commercial openings.

This concealed overhead stop is used on commercial-grade interior doors where a clean, hardware-minimal appearance is required. Its concealed mounting keeps the mechanism hidden within the door frame head, making it a common specification in healthcare, education, government, and hospitality environments. The Satin Stainless Steel finish provides corrosion resistance in high-traffic or humidity-exposed corridors. The heavy-duty Size 3 designation indicates suitability for larger or heavier door leafs common in commercial construction.
