Aluminium 25 mm SL, överdel med gångjärnskoppling, presspassning

Illustration: The left-hand side of the profile is on the inside. The profile equates to a bottom end profile in the coupling area; only upper or middle profiles can be clipped in as a connection. 612910 and 621294 together form an upper end profile with linkage, which can be used for adjusting butterfly flaps, for example. The result is a smooth outer area that can be optimally used as an advertising space. The snug fit or positive-fit connection of the upper end profiles to the connecting element eliminates the need for additional sealing of the flap in this area. Maximum angle of beam 94°.
