The AGx is an x-shaped wall spike designed specifically to refine urban landscapes. AGx shares the same core concept and composition as the multi-award winning first edition “AG”, yet with an even simpler physical form. Aluminum extrusions are cut diagonally to provide the sharpness required for security and improvements to the new structure enhance the AGx's functional beauty. The x-shape, expressing prevention of intrusion, is composed of smooth lines and assembled in rhythmical queued units to harmonize with any landscape.
