Abstract
A disc dowel system is interposed between adjacent first and second concrete pours defining a pour joint therebetween. The disc dowel system comprises a pocket former having a rib insert disposable therewithin for engaging the sides of a dowel plate. The pocket former has a vertical base flange with a pair of fastener-receiving bosses for securing the pocket former to a concrete form. The pocket former has a horizontally extending interior compartment with an open straight side that is aligned with the pour joint and is positioned within the first pour. The dowel plate has an orthogonal shape with an embedded portion and a slidable portion. The embedded portion is rigidly encapsulated within the second pour. The slidable portion is slidably disposed within the pocket former such that the dowel plate permits relative horizontal movement of the first and second pours while restricting relative vertical movement thereof.
