ColorGard is manufactured from mill-finished, aircraft quality aluminum. It comes in long sections, in unpunched configurations. Splices are included with ColorGard for adjacent sections. For use with S-5!® heavy duty clamps, VersaBracket™ and CorruBracket™. Unpunched ColorGard is the most versatile and easy to install, when used with the S-5!® VersaClip™. Unpunched does not need holes, as the VersaClip accommodates any seam spacing. The unpunched configuration works well with VersaBracket. Unpunched is the right choice when the roof is laid out with untrue seam width or when the seam width is not divisible by 4. If in doubt, use unpunched.
