Stackable builder's sieve for plaster or cement powder

摘要

The builder's sieve comprises a body (1) and a metal grille (7) fixed to the bottom of the body. The body is made of plastics, with the edge of the grille held inside the plastics. The metal grille is gripped between the bottom of the body and an external plastics ring (8) soldered to the body so it encloses the edge of the grille. The body is conical with a diameter decreasing from top to bottom, so the sieves can be stacked one inside another. Contact points are mounted at regular intervals around the outside face of the sieve body, and rest on the horizontal edge of the next sieve down in the stack.
