Surface box for valves height adjustable, with locking bolt

The Hawle surface box for valves is preferably used for installation in bituminous traffic areas.
Installation in paved areas with sand or chippings grouting is not possible. In this case, the rigid version of the surface box for valves or gate valves ord. no. 180-00 must be used.
For height adjustment extension rings ord. no. 181-01 or 181-02 can be used.

Compared to conventional surface boxes the angle seat at the cover and the box provides for reduced rattling of the cover.

To avoid contact corrosion between the cover and the box, on the one hand, and to ensure that the cover comes loose easily, on the other hand, the latter is powder-coated.
