Abstract
The invention is a method, an apparatus and a kit of parts for assembling a universal frame with at least two jambs, a lintel and a sill. The resulting frame is suitable for any size of opening and any size of door, with the option to include single doors or double doors as well as side screens and/or side lights. The frame is typically assembled by cutting the jambs (and optionally the sill and/or lintel) to a selected size, attaching keys to each end of each jamb and inserting the keys into keying channels in the sill and lintel.

- providing or forming a lintel of a selected length, the lintel having at least one keying channel running along at least part of a longitudinal surface of the lintel;
- providing or forming at least two jambs of a selected length, each jamb having keys extending longitudinally out from a top end and a base end of the said jamb, said keys shaped to cooperate with and be retained by said keying channels;
- inserting the keys at one end of each jamb into the at least one keying channel of the lintel;
- and
- inserting the keys at the other end of each jamb into the at least one keying channel of the sill, to thereby form the frame,
- such that each keying channel faces an aperture of the frame.
