<p>A plastic base plate has two half-pieces placed on it. The top and outer edge of the base plate have a projecting rim which fits round the two mesh half-cage sections. A number of vertical, elastic inside flaps fix the two half-cage sections in place. A retractible drawer in the base plate has a vertical projection around it. The half-cage section has a round steel bar going round the top side joining the section to the middle piece. The top of the middle piece is in the form of a grille (6) with two round steel bars on the sides, identical with the round steel bars of the top plate of the half-cage section. The sets of round steel bars are joined to those of the half-cage by two plastic strips (7) which have a side L-shaped guide piece (8).</p> |
