ABSTRACT:
Method and apparatus for forming a grommet assembly to seal and reinforce holes through a cured in place liner for securing a cable. A first grommet base having a centrally located aperture with wedge shaped grooves is positioned on one side of the hole. A barrel having two opposed sets of wedge shaped projections is inserted into the grommet base and a second grommet base is placed on the barrel and pushed towards the liner until the second base firmly contacts the top surface of the liner and compresses the liner against the first base. The wedge shaped projections on the barrel and the complimentary grooves in the central apertures of the grommet bases prevent the barrel from being pulled out of either grommet base. The end of the barrel which projects out above the second base is cut off flush with the top surface. A hydraulic press to install the grommet assembly is also disclosed.
