Long in development and testing, astec has just announced the release of their glass door closer for their floor-bearing b.400/410 wheels. The closer sits up in the “guide” channel which previously house the door stops on either end. With this development you can get a softclose effect on both ends of an 8ftx8ftx.5in piece of glass.
This is an excellent feature for large doors and especially in public spaces can be a highly recommended safety feature. These big doors can pick up speed.
