Door-frame corner or cross arm connector - with central cutout for joint sealing accessible via external cutout and channels

摘要

The corner or cross arm connection is for window or door frame, or other frame, shaped-sections, using a mitred or cross arm-connector engaging in the shaped section ends. There is a central cutout (21) or hole in this unit (14) for filling the abutting joint gaps (15) of the connection (11) with a sealing mass (20) from inside, and this is accessible from outside via a cutout (22) in one of the shaped-sections (12). One or more channels (23-25) or cutouts are worked into the unit, connected to the central cutout or hole, and these lead to the points, between the frame shaped-sections, which have to be sealed.
