Committed to quality since 1923

AceClamp® is a market-leading manufacturer of rooftop snow retention and solar mounting systems.  Our lab-tested mounting systems help save contractors time and money by offering fully assembled clamps and component groups, simplifying the installation process, and reducing overall labor costs.

Over the years, traditional set-screw clamps have been found to cause stress cracks and puncture damages to various metal roofing surfaces that could cause leaks, rust, staining, and even compromise the manufacturer's warranty.   AceClamp's solution is our patented non-penetrating, sliding-pin metal roof clamps, which secure rooftop fixtures to metal roof seams without the need of rotating set screws.   Secured by a single fastener, AceClamps evenly distribute forces across its two push-pins, providing a secure connection with the least surface disruption possible.  And while AceClamp is helping to protect your customer's roof from installation damage, it installs up to 2.5x faster* than the traditional set-screw clamps.

Another example of AceClamp's time-saving ingenuity can be seen in Color Snap®, a snow rail system that features snap-in Ice Flags, which installs in a "snap" anywhere along the rail without screws.  Color Snap also allows roofers to slide in a strip of roofing material to match the rail color to the roof, helping architects and engineers to maintain an elegant, seamless look for the client's projects.

We carry a full assortment of accessories for both snow and solar attachment solutions. While our products are designed primarily for standing seam metal roofs, we offer asphalt, membrane, and slate solutions. All of our products are tested for both wind uplift and snow loads.

We've been committed to quality and innovation for four generations, with our beginnings as Wasley Family of Products. AceClamp is one example of how this family-owned manufacturing business has continued to innovate and manufacture quality products here in the United States that meet the needs of consumers and industries worldwide.

Our 55,000 square foot facility manufactures and sells high-quality products for the medical, aerospace and automotive industries. Our patented AceClamp, a non-penetrating solution for solar panels, satellite dishes, and snow retention devices for standing seam metal roofs, is our most recent innovation to meet the needs of consumers. Get on and off the roof faster™! Laser etching and barcoding are available.
