Duradowel is a patented dowel system combining a high-density plastic sleeve with an ASTM A36, hot rolled steel plate. What makes our dowel system better is a combination of time saving and quality enhancing features. Our unique Die-Loc design features gussets  specially designed to prevent crushing as-well-as keeping the sleeve in place while removing forms. Additional nail holes above and below the sleeve allow for added strength to fight downward & upward forces from concrete. Horizontal notches allow for proper sleeve alignment with forms. Tapered, funnel nail guides make nail insertion fast and easy.
