Claim:
1. A slide rail assembly comprising: a first slide rail having an end configured to be attached to a first mounting post proximate a first side of a cabinet and including a first elongated web plate which has a front surface facing toward a carried item and a back surface facing away from the carried item in use; a second slide rail nested within a slide chute of the first slide rail and comprising a second elongated web plate having a recess therein extending along the length of the second web plate, the second slide rail being movable relative to the first slide rail along a length of the first slide rail, wherein the first slide rail comprises a first L-shaped upper folded panel extending from an upper edge of the first web plate at an angle of about 90 degrees with regard to the back surface of the first web plate, a horizontal supporting panel for supporting the item extending from a lower edge of the first web plate at an angle of about 90 degrees with regard to the front surface of the first web plate, and at least one first L-shaped lower folded panel extending from the lower edge of the first web plate at an angle of about 90 degrees with regard to the back surface of the first web plate in a direction opposite that of the horizontal supporting panel, with the first upper folded panel and the at least one first lower folded panel form the slide chute for the second slide rail, wherein the second slide rail comprises a second L-shaped upper folded panel extending from an upper edge of the second web plate at angle of about 90 degrees with regard to the back surface of the second web plate and a second L-shaped lower folded panel extending from a lower edge of the second web plate at an angle of about 90 degrees with regard to the back surface of the second web plate and further comprising a third slide rail nested within the second slide rail, the second upper folded panel and the second lower folded panel forming a slide chute for supporting and guiding the third slide rail, the third side rail having an end configured to be attached to a second mounting post proximate a second side of the cabinet, wherein the third slide rail comprises a third elongated web plate having at least one elastic panel punched out, wherein a side surface of the outer end portion of the at least one elastic panel towards the second web plate of the second slide rail is provided with a first protrusion, wherein the second web plate has a recess or through-hole for receiving the first protrusion in a retracted condition of the slide rail assembly, and wherein the third web plate has a second protrusion which forms a tight fit with an inner side surface of the first slide rail in a retracted condition of the slide rail assembly.
