A threaded anchor for embedding in a cementious material comprising a unitary member of generally cylindrical configuration, which is interiorally threaded and open at one end. The other end thereof is closed by a base portion of greater size than the diameter of the cylindrical member, said base portion being disposed perpendicular to the longitudinal axis of the cylindrical member. On the exterior surface of the cylindrical member are a plurality of radial flanges, which extend along the length of the cylindrical member, and are attached to the base portion. The threaded anchor is preferably formed from a single sheet of metal. This sheet is fed into a drawing device, whereon the sheet is drawn into a cup shaped member having a closed end. The cup shaped member is placed over a mandrel and the exterior surface of the member is then pinched with means of shorter length than the length of the cup shaped member to form radial flanges on the exterior of the cup shaped member, and a flange at the bottom of the cup shaped member to which the exterior surface flanges are attached. The threads are then formed on the inner surface of the cup shaped member.

Threaded anchor

A seal for a duct terminator, that is adapted to be formed with an underground utility vault, is secured to the bell-mouth portion of the duct terminator, and is operative to facilitate the molding of the utility vault, and after being embedded in the utility vault, provides additional seals to prevent water from entering the utility vault. The seal is an endless, flexible member having a generally H-shaped cross-section, with two of the legs of said seal being adapted to engage the bell-mouth end of the duct terminator, while the other two legs are embedded in the concrete vault so as to provide two sealing or water stop means to prevent water from entering the vault when the latter is subjected to thermal expansion and contraction.
