Abstract: Provided is an improved concrete dowel placement apparatus having a base member including a base plate that is disposable on the outer surface of the concrete form, and an extension member that extends through an aperture located within the concrete form. In this regard, the base member is supported by the concrete form, and is therefore generally configured to withstand higher loads than the conventional prior art designs. Furthermore, the particular attachment configuration spaces the base plate from the concrete slab, which generally prevents the base member from becoming embedded within or adhered to the concrete. As such, removal of the form from the cured concrete tends to be much easier than removal of conventional prior art systems. In addition, the base member is less likely to crack or break during removal, which reduces the overall cost, as fewer base members may need to be replaced.

Abstract: A hoist ring assembly with expansion anchor includes an anchor subassembly and a rotatable and pivotable lifting loop. The anchor subassembly includes a bushing element, an engagement element and a retainer element. The bushing element has an anchor shaft extending along a major axis.
