This robust solution is the perfect answer to your trapezoidal sheet mounting needs. The unique clamping on the crown mechanism effectively converts pull-out forces into shear forces, granting it exceptional clamping strength compared to top-down attachments, making it highly resistant against wind uplifts. Additionally, the side clamping feature ensures superior thread engagement and stripping torque capacity, further enhancing the system’s strength and stability. We are in the process of developing an even more optimised version for enhanced usability and convenience.
