Mount a variety of rooftop accessories with zero penetration to your roof.

S-5! clamps are offered in two sizes to accommodate the holding strength needs of varying utility applications. Our standard (two-setscrew) clamps are designed specifically for heavy-duty applications, such as snow retention, and they provide documented and unsurpassed holding strength. Mini (one-setscrew) clamps save considerable cost for medium or lighter-duty applications, like satellite dish or solar panel mounting.
