Commercial and institutional projects require investing in quality doors, frames, and door closers by limiting the force of door swing. With high traffic and abuse, extending the life of your opening with an overhead is the way to go . Typically overhead models come in different sizes and functions, making it complicated for customers to stock, specify, install, or order exactly what you need.
The new Glynn-Johnson 510 Concealed Series and 550 Surface Series heavy duty, adjustable overhead makes your investment not only smart, but simple. Simply stock one 510 or 550 and it is versatile enough to replace dozens of skus in inventory, making this the most comprehensive overhead available in the market today.
