Abstract
A manhole lift insert positioning apparatus consisting of: (1) a threaded nut imbedded in a thermoplastic elastomer molding that fits snugly within a lift insert, and (2) a threaded wing bolt to engage the nut and expand the molding within the insert, thereby locking it in position and drawing the molding against the inside face of the concrete form, thus sealing the insert opening to avoid obstruction of that opening with concrete.
