Abstract
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.
