ABSTRACT:
A distributing box for laying a cable duct is dealt with in the construction field so that, after laying the cable duct, the box is sealed with mortar and then buried in the ground. Accordingly, the distributing box should desirably be set up in the construction field with ease. Underground water must not permeate the distributing box which has been buried in the ground. In the present invention, therefore, a distributing adapter which is mounted in the wall of a concrete box is constructed of a case which has a back plate, a partition wall which divides the interior of the case into a plurality of areas, a flange which is formed at the periphery of the case, and marks for drilling positions, which are put on the rear surface of the back plate.
