<p>An angular piece, engaging chambers at the profile piece ends, and connected to them, provides corner connection for frame profile pieces in windows or doors. To permit application of adhesive (31), the angular piece (11) has a recess (14) on one side of a shank, at least, aligned pref. perpendicular to this and extending over all or part of its width. This is in contact with an aperture (15) worked in one or both frame profile pieces (2-5) and accessible from outside. The recess may be on the inside, in the corner area of the two abutting faces. Corner joints can be quickly, easily and economically effected, with no risk of health hazards from adhesive.</p> |
