Undermount drawer slide

An undermount drawer slide comprising:

• a cabinet rail comprising an L-shaped bracket having a first part adapted for mounting to a side wall of a cabinet and a second part extending away from the first part, and an offset flange extending from a longitudinal edge of the second part, the offset flange comprising an offset and a flange;
• an intermediate rail comprising first and second channel shaped bearing raceways interconnected on one side by a web of the intermediate rail and forming a mouth opposite the web, the flange of the cabinet rail extending into the mouth, with edges of the second channel raceway including angled abutments extending away from the second channel raceway;
• first bearings coupling the first channel shaped bearing raceway and the flange;
• second bearings coupling the second channel shaped bearing raceway and the flange;
• a shelf rail having a substantially C-shaped cross-section with side bearing raceways interconnected by a web, the web forming a further raceway;
• third bearings coupling the further raceway and a raceway of the intermediate rail between the angled abutments;
• fourth bearings coupling each of the side bearing raceways with raceways of the intermediate rail on sides of the angled abutments opposite the angled abutments from the raceway of the intermediate rail between the angled abutments.
