Patent ID: 8069532

Claim:
A grommet for reinforcing an opening in a cured in place liner, comprising: first and second grommet bases each having an outer surface and an opposed inner liner facing surface with a central opening extending between the two surfaces; each grommet opening having a securement surface; and a barrel having first and second securement surfaces adapted for engaging the securement surfaces of the grommet bases when the barrel is inserted into the central opening in the grommet bases, the first and second securement surfaces of the barrel being oriented in opposite directions such that engagement of the first securement surface with the securement surface of the first grommet base prevents nonrotational movement of the first grommet base in a first direction and engagement of the second securement surface with the securement surface of the second grommet prevents nonrotational movement of the second grommet base in a second direction which is opposite the first direction.
