Abstract: A conduit support apparatus for concrete installation which, in the preferred embodiment, includes a collar portion supported above a concrete form by at least one support member, the concrete support apparatus fastened to the concrete form with fasteners which pass through holes in horizontal bottom sections of the support member and into the concrete form, the dimensions of a preferred embodiment of the conduit support apparatus being uniquely balanced to impose a bend on a supported flexible conduit with a curvature within an optimum range of curvatures which is defined between two undesirable limits described by a first small curvature which results in the upper section of the conduit bending back into the form space and a second large curvature which results in the flexible conduit collapsing into itself to reduce the amount of work space within the flexible conduit below an acceptable level.
