The Watts Dead Level pre-sloped trench drain system’s frame-loaded design absorbs dynamic traffic loads through the structural frame, protecting the polypropylene channels from stress and failure. The self-aligning channels lock longitudinally outside the structural frame and cannot pinch or fold in during concrete pour. Flanged joints create positive, stable connections and enable rapid installation, resulting in dead-straight drainage runs.
