<p>The corner connecting system for hollow profile units in frame construction is esp. for aluminium windows and doors. It provides easy mass production, assembly, dismantling if necessary and transport. Using the corner connecting pieces introduced into the hollow profile units, the latter are braced together by clamping pieces and clamping screws. The corner connectors may have holes for strips, for aluminium windows or door leaves or for screw linking several frame components together.</p> |
