Abstract (en)
A surface box for housing valves, taps etc. in the ground comprises a tubular lower portion (1) and a tubular upper portion (2) which fits as a sleeve around the lower portion and can be seated on the lower portion in any one of a plurality of positions of relative rotational adjustment between the two, determining different heights fora top surface (S) of the box above the lower portion. The upper and lower portions together form an access passage through the box in all positions of rotational adjustment. A removable closure member (3) is received within the upper portion to close the passage. The lower portion (1) of the box has three sets of common-level seating faces (7,8,7,8',7'',8'') which co-operate with seating faces (15,16) of the upper portion (2) in each position of adjustment to provide different height settings. The upper portion has bearers (12,12',12'') on an inside surface (10') to engage the lower portion and to support the removable closure member. <IMAGE>
