摘要

Each frame upright and crosspiece comprises a base element constituted by a first section (1). At least one upright or crosspiece comprises a complementary element intended to be fixed to a construction wall and to the base element. The complementary element is constituted by a second section (21) chosen from a set of sections dependent upon the thickness of the wall in which the construction open is located. The two sections are clipped together by means of a groove in the first section side which receives a lip (29,32) in a side of the second section.
