Abstract
A concrete dowel slip tube assembly is provided for use in maintaining a planner consistency of a cured concrete slab formed on a support surface. The assembly comprises a plurality of elongate slip tubes, each having a length dimension and a tubular hollow interior compartment. Dowels are slidingly engageable to the hollow interior compartment to allow for translation along the interior compartment. A support frame defines a plurality of integral slip tube retaining members, disposed at evenly spaced locations along the support frame, the retaining members being configured to receive and engage associated slip tubes to the support frame in a common defined orientation. The support frame and the retaining members are formed as a unitary construction.
