  • Concrete plate and sleeve dowel device with break-away alignment tabs
    Patent number: 9574309
    Abstract: A concrete dowel device including a sleeve and plate in which the sleeve includes break-away alignment tabs at the opening of the sleeve to ensure proper alignment of the plate within the sleeve during field installation. The tabs are positioned at the sleeve opening, rather than along the length of the socket, to avoid misalignment of the plate in the sleeve, simplify use and reduce manufacturing costs of the product. The sleeve and plate may include additional alignment surfaces on the plate, at the rear corners, or along the rear side of the plate and sleeve. To facilitate manufacturing, the break-away alignment tabs may be formed as molded components rotated and snapped into position. Alternatively, the break-away alignment tabs may be formed as part of an insert plate manufactured apart from and attached to the flange of the sleeve.
