Abstract: Improved draught excluder for fastening doormats, of the type formed by an elongated prismatic body, consisting in that the prismatic head is formed by a sheet, in that it has, along its side, a “T”, and in that its transverse arms are free, one of them being bent at right-angles.

Abstract: The invention consists of several improvements introduced into the construction of mechanical draft excluders for the lower edge of doorjambs, characterized in that the body of the draft excluder is built in three sections aligned horizontally, with the two end sections each connected to a side of the doorjamb and the third laid out in a sliding fashion between the two to cover the separation that might exist between the two fixed end sections by adapting to the width of the door.
