X-Clip II™ is an optional component that can be added to your X-Gard 1.0 or X-Gard 2.0 snow retention system to further retard the migration of snow. X-Clip has a special integrated rubber “foot” to prevent abrasion of the panel’s finish. It rests on the back of the NEX® 2.0 Pipe and extends down to the flat of the roofing panel. X-Clip II™ is especially made for seam heights of 1″ (25 mm) and 1-3/4″ (44.5 mm). It will also fit 2″ (51 mm) vertical seams, but not 2″ (51 mm) horizontal.
