Abstract: A locking lid and method for a valve box. The locking lid has a closure and surrounding external seal, which fit into the valve box opening and close/seal it. The locking mechanism of the locking lid preferably consists of an actuator spindle that extends through the closure, and that is received in an actuator follower positioned therebelow. The actual follower is in pivotal engagement with a plurality of locking pawls, such that turning of the actuator spindle causes movement of the actuator follower and thus pivoting of the locking pawls—moving the locking pawls into a locked or unlocked position relative to a lid seat within the valve box.

Abstract: A debris cap apparatus and method, which provides a secure and debris resistant seating of a debris cap within a valve box. The debris cap has two outwardly projecting annuli—a debris seal located near the top of the cap and a retention gasket located distal from the top of the cap. The debris seal blocks debris from entering the valve box when the debris cap is in position. The retention gasket is designed to be pushed down past an inwardly projecting flange within the valve box, to deform as it passes the flange, and then to resume its original shape when past the flange so as to preclude accidental dislodging of the debris cap from the valve box. Where the debris cap is to be used within a pre-existing valve box, an adapter may be provided. It is further preferred to provide a removal tool so as to permit ready removal of the debris cap from the valve box or valve box adapter.

Abstract: Lid 12 has affixed thereto an annular resilient flap 26 which cooperates with a flange 21 on a lid support 13 to resist dislodgement of the lid. The flap 26 i worked into position beneath the flange 21 by rotation of the lid about its axis. A container portion 34 of the lid may contain a granular material to add weight to the lid.

Abstract: A cap body has a movable retaining tongue which is engageable with a portion of an access structure to retain the cap on the structure. A tongue is manipulated through a bolt, the head of which is accessible at the top surface of the cap body. A cover for the bolt head has a locking post which extends through the cap body and engages and locks the tongue against movement.
