Standard perforation patterns and selected finish options are shown below. A wide array of custom perforations and unique finishes can be created to achieve your specific design objectives. Contact Gordon for details.

Please contact Gordon for design assistance with your guide specifications. Not all perforations can be used with every application. Material type, thickness, module size, and ceiling type must be taken into consideration when selecting the appropriate perforation pattern.
