Sliding door assembly

A method for interconnecting at least two hollow elongated extruded sections of a door sash, each said hollow elongated section having at least one beveled mating end and at least an outer end wall defining thereagainst an internal hollow elongated channel, comprising the steps of:

• i) inserting a first one of two arms of a right-angle connector in said internal hollow elongated channel of a first one of said hollow elongated sections from said beveled mating end thereof, said right-angle connector having in each said arm an abutment protrusion disposed at a predetermined location and abutting an inner surface of said outer end wall;
• ii) inserting a second one of said arms of said right-angle connector in said internal hollow elongated channel of a second one of said hollow elongated sections from the beveled mating end thereof until the beveled mating ends of both said hollow elongated sections abut one another;
• and
• iii) forming a crimp in said outer end wall of both said hollow elongated sections at a predetermined location to form arresting shoulders under said abutment protrusions to interconnect said hollow elongated sections with a respective arm of said right-angle connector and with said beveled mating ends in contact with one another.
