ABSTRACT:
A concrete dowel placement apparatus comprising a base member and an elongate, tubular dowel receiving sheath which is connectible to the base member. The base member comprises an outer sleeve having first and second ends and a flange portion which extends about the first end of the outer sleeve and defines front and back surfaces and a peripheral edge. The base member further comprises an inner sleeve which is disposed within the outer sleeve and defines an aperture extending longitudinally therethrough to the back surface of the flange portion. Extending between the inner and outer sleeves is at least one reinforcement wall. The sheath has an open proximal end, a closed distal end, and a hollow interior compartment extending longitudinally therein. The open proximal end of the sheath is extensible over the outer sleeve such that at least a portion of the outer sleeve resides within the interior compartment.
