Hinge System

Neenah Foundry has advanced municipal castings to a whole new level of function and safety. Our patent pending LiftMate™ Hinge System eases operation and access while virtually eliminating many traditional hazards of working with covers for manholes, grates and trenches.

The LiftMate™ Hinge System provides a controlled motion pivot that helps protect workers from excess strain or off-balance maneuvering. That helps prevent on-the-job accidents as well as reduces lost-time injuries.
