The access cover (12) is connected to the body (1) of the hydrant by a housing (10) with an assembly interface which limits relative movement between them. The movement limiter incorporates a regulator (20) for the relative vertical positions of the housing and hydrant body, having upper and lower stops (22a, 22b) and a position adjuster (25), e.g. in the form of a threaded rod (26) and nuts (27). |
