A telescopic drawer slide comprises a casing slide 11, a drawer slide 10 and an interposed extension slide 12 carrying rollers 22-25 and having a simple channel section formed solely by a web 19 from opposite edges of which flanges 20, 21 extend at right the angles, the web 19 having three punched out tabs 33, 34, 36 forming stops. One tab 34, at the front end of the extension slide 12, is bent inwardly to overlie the top 15 of the drawer silde 10 to limit upward displacement of the slide 10. Another tab 33 engages ends 18 of a recess 17 in a flange 14 of the drawer slide 10 to limit relative longitudinal movement of the extension and drawer slides 12, 10. The other tab 36 engages a slot 44 in the web 41 of the easing slide 11 to limit relative sliding of the casing and extension slides 11, 12. Tongues 45-47 pressed from the casing slide web 41 engage apertures in the casing to support the slide 11. A roller 38 is received in a recess 54 in the bottom flange 42 of the casing slide 11 when the drawer is closed. |
