These wedges are made from a special steel alloy which gives shape memory properties to the wedge. This way, when it penetrates into the moulding, it spreads its wings which -because of shape memory- try then to come back to their initial position.
This results in pulling very strongly the 2 pieces of mouldings towards each other, so as to give a perfectly closed corner.
(2)Thin pieces of wood that are inserted into the corner of two mitered frame lengths to join them together.
