Captive Hinge Access Assembly

 Captive Hinge Access Assembly

Manhole cover remains permanently attached to the frame

The Captive Hinge Access Assembly is an advanced solution that addresses present concerns in the market such as cover theft, ergonomics, safety, pressure relief, and security. Once a cover with a captive hinge pin is installed, the cover cannot be removed.

Hinged Design

The Captive Hinge Access Assembly has a hinge design that allows for flood pressure relief—the lid remains attached in cases of extreme flood pressure. The lid opens to 120° but features a safety catch at 90°. The non-slip surface and light weight ductile iron frame and cover increase worker safety during installation and maintenance.
