Abstract
Conduit retainer apparatus includes a central bridge element and a pair of end plates secured to the central bridge element. The conduit retainer apparatus is disposed in a trench on top of conduits. The end plates dig into the sides of the trench to prevent the conduits from rising or floating as the conduit is being encased in concrete. The end plates include barb elements to help lock the conduit apparatus to the sides of the trench. Different configurations of barb elements are illustrated, and also different embodiments of end plates and bridge elements.
