SPARKLE access cover - keylock assembly

This access lid keylock assembly is designed for supportive access into an inground device. The keylock assembly is installed in the lid to provide a keylock seal on the PE lid. This has the effect of easy access to the device and to secure the lid from unintended access or back surge of the device applying flow forces on the underside of the lid tending to cause the cover to rise off its seating. The Keylock is installed in the tank to assist entry and egress from the tank. When closed, the assembly can act as a barrier and prevent accidental tank entry and provide additional support for the manhole cover.
