Clamp Resists Wind Uplift and Seismic Vibration

Installers of attachment systems on standing-seam metal roofs (SSMR) can now rest assured their roofs will resist wind uplift and seismic vibration with the A2 AceClamp. The A2 AceClamp’s unique design virtually eliminates the need for periodically re-torquing clamps to preserve manufacturers’ warranties, as is recommended for other SSMR clamp systems.

The A2’s innovative solution prevents torque back-out, caused by wind flutter or constant seismic vibration, by employing a distinctive “push-pin” design that locks two stainless steel pins into the roof panel to secure the clamp. The design effectively prevents loosening or torque back-out and is Patent-Applied-For.

Prior to the A2, manufacturers relied on round or concaved-headed set-screws that turned and rotated into the metal roof’s surface to penetrate and lock into the metal seam. This typically resulted in scratches or damage to the panels’ surface. The A2’s sliding push-pin design eliminates this concern. The A2 solution does not damage or scratch the panel surfaces, thus upholding manufacturers’ warranties while assuring one of the strongest clamp systems in the industry.

For solar-racking installations, the A2 saves time and additional costs where grounding cable brackets are used. The A2 is designed with a grounding cable groove in the clamp. A stainless-steel sleeve and set-screw kit securely hold the grounding wire in place. For the installer, this feature eliminates the need for a separate grounding attachment, as the cable groove is incorporated into the clamp itself. The stainless steel sleeve also prevents corrosion of the grounding wire while enhancing electrical conductivity.
