    Easy-to-Install. The compound root radius in the element teeth increases flexibility for easier and quicker assembly. Can be blind assembled from either direction.

    Tough, Long-Lasting polyurethane "Wrapflex®" element has excellent wear and chemical resistance, and an operating temperature of -40° F to 200° F. Weather-resistant, high-grade nylon cover is standard.
