An undermount slide assembly includes an outer slide segment, an intermediate slide segment and an inner slide segment. The outer slide segment has a web, a first flange and a second flange. The web defines an upper surface that is mountable to a first object. The intermediate slide segment has a web, a first flange and a second flange. The web is received within a space defined between the first and second flanges of the outer slide segment. At least portions of the first and second flanges of the intermediate slide segment extend below the first and second flanges of the outer slide segment. The web and the first and second flanges of the intermediate slide segment define a space therebetween. An inner slide segment is received within the space defined between the web and the first and second flanges of the intermediate slide segment.
