Hinged Trench Assembly

Ergonomic drainage solution for supply lines and collection systems

The hinged trench assembly simplifies access for supply lines and collection systems. Available with hinged covers or grates, the system can be configured to any length of trench needed.

Optional mechanical strut improves ergonomics by reducing lifting force to 35 lb or less for the entire range of motion—available for both cover and grate versions.

The covers offer optional cable cut outs for electrical, telecommunications, and other supply lines to be temporarily exposed for use while the covers remain in the closed position.
