Abstract
A trench duct power compartment for use over a cellular raceway is fabricated by forming a rectangular-shaped blank and then stamping out a center section to leave portions which are contoured to the shape of the crests of the cellular raceway and thereafter bending the cut-out blank to simultaneously form upright side walls, downwardly extending concrete blockers together with connecting bottom end sections while leaving the bottom midsection open. The contoured portions of the concrete blockers having the same profile as the crests of the cellular raceway and snugly engage therewith.
