T-Lock Manholes

T-Lock Manholes (36" I.D. - 144" I.D.)

Like all other parts of the sewer system, manholes are susceptible to corrosion and, therefore, must be protected or they will ultimately fail. The T-lock Liner Precast Manhole system is designed for new construction and replacement sanitary sewer manhole applications to provide complete corrosion protection.
