Marchon Airlock has redefined rimless collections forever. The Airlock mounting system uses a barbed taper at the end of each frame mounting. When the bushing and barbed taper are pressed together, a secure fit is created that far exceeds that of any other screwless mounting system.

 

Airlock uses pressure rather than screws to keep the lens in place. Minimal frame components means lighter weight. This is further optimized by using high quality Beta-titanium to construct the frames. Beta-titanium is the most flexible alloy of titanium.
