The access chamber consists of a circular base (1) with a raised threaded edge to engage with the inner surface of a truncated conical body (2) with a series of holes (A2), made e.g. by pre-cut lines, for the conduit ends. The upper end of the body has a collar (C2) to receive a cap (3) with pre-cut lines to allow it to be cut to the required height. The components can be made from wood, concrete, plastic steel or resin. |
