Rooftop attachments from fall arrest to solar mountings

S-5! is the proper way to attach almost anything to standing seam metal roofing- from service walks, satellite dishes and photovoltaic solar modules to fall protection and snow retention devices. Patented S-5! clamps make the attachment without penetration of the panel seam material.

Unlike methods that use sharp or ‘cup’ point screws to dig into or pierce the metal, damaging fragile finishes and violating warranties, the S-5! method utilizes a patented combination of polished round-point setscrews and machined reliefs to allow a secure and positive mechanical gripping of the seam with no ill side effects.

Roof accessory mounting

Dependable and consistent S-5! attachment methods mean that holding strength is laboratory tested and published at the S-5! website. S-5! clamps are machined from non-corrosive metals- never brittle castings or synthetic materials. They also utilize stainless steel hardware. S-5! clamp models are made for every conceivable seam material, finish, profile and gauge. If the right hardware is not available for your application, we’ll custom make it. Technically correct, fully engineered, as lasting as the roof itself, S-5! provides an affordable solution to any rooftop-mounting problem.

ColorGard© is the only snow retention system designed and engineered on a sitespecific basis; guaranteed to perform, to not damage the roof or finish, and to exactly match the roof color for the entire life of the roof.

ColorGard is mechanically attached with patented S-5! clamps – S-5! is the trusted name in metal rooftop attachment technology worldwide. S-5! patented, round-point setscrews grip the seam securely without penetration and without damage to the panel’s protective finishes. The clamps are precision-machined from aircraft quality, high tensile aluminum— not cast or plastic. All related hardware is non-ferrous stainless steel for lasting performance.


When snow accumulations begin to melt, the result can be catastrophic as the blanket of snow avalanches off the roof dumping tons of snow onto anything in its path. It can damage landscape, gutters, adjacent roofs, vehicles, and cause injury or death to passers-by. SnoRail/ SnoFence dramatically reduce these risks associated with rooftop avalanches, maintaining the clean lines of the roof and lasting as long as the roof itself! SnoRail / SnoFence can be designed and engineered on a site-specific basis.

Architects and roof designers agree: the clean lines, cylindrical shapes and high-tech look of our SnoRail™ and SnoFence™ systems present an attractive solution to snow retention problems! They function without cluttering the lines of the roof. With up to six times the strength of adhesively mounted devices, and without the high labor costs and inconsistencies of soldered snow guards, S-5! offers the perfect, long term, dependable solution for traditional standing seam and sheet copper roofing.

The SnoRail and SnoFence systems are mechanically attached with patented S-5! clamps utilizing our patented round-point setscrews – designed not to “pin” or “fix” the roof panels to the building, leaving thermal movement unrestricted. The clamps are precision-machined from aircraft quality, high tensile aluminum—not cast or plastic. All related hardware is non-ferrous, compatible stainless steel for lasting performance.
