Abstract
A concrete joint restraint system that is adapted for securing a dowel to first and second horizontal members that are spaced apart from one another and located at a desired height above a subgrade prior to placement of concrete. The system includes a closed clip including a cylinder with an end aperture for receiving one end of the dowel and a snap-on connection for connecting the open clip to the first horizontal member. The system further includes an open clip including a pair of flexible, arcuate side walls that define an elongated gap for receiving the other end of the dowel and a snap-on connection for coupling the closed clip to the second horizontal member. The system beneficially permits plastic, fiberglass reinforced plastic, or other non-metallic dowels to be supported between inexpensive rebar bolsters made of steel wire.
