Plate Dowel System

The Convex Dowel System offers a plate dowel that can be used in all concrete flatwork applications, and is the only one that can be used for longitudinal joints in slip form paving. The system consists of a tapered plate dowel, whose parabolic shape allows for positive load transfer in all directions, a saw blade, which can cut slots for 1/4-, 3/8-, or 3/4-in. plates, and a ride-on installation machine that includes an onboard dust collector and can cut over 1440 slots in an eight-hour shift.
