Invention refers to mounting or distributing box consisting of adjusting ring (2, 3) attached to internal perimeter (8) of orifice of case (1) of box and travelling into required adjusting positions before connection. Adjusting ring (2, 3) consists of two rings. Also the first, proper adjusting ring (2) is made by means of two-component process and includes connecting ring (6) out of elastic material. The second ring (3) is made in form of a wedge-shaped ring displaced with clamp screws (4) relative to the first ring (2) to compress elastic ring (6), thus expanding elastic ring (6) radially outside for connection by engagement with internal perimeter (8) of the box case. Wedge-shaped ring (3) is equipped with blocked teeth (9) bent outside in response to compression of screws (4). The ring is attached to internal perimeter (8) of the box case by means of connection through engagement. |
