Hettich Logo

Hettich KA 3320 telescoping precision full extension 18" drawer slides for high loads, up to 500 lb. capacity, with cushioned in and out stops. The runner and ball race form a single non-detachable unit. The 18 inch drawer runner is not removable. You will need to unscrew the drawer from the runner to remove the drawer box. The reason for this is with 18 inches of travel to its fully extended 36 inch length, the weight of the loaded drawer acheives a great deal of momentum and must come to an abrupt stop. A lever release would need to be massive and would be expensive and hard to fit into the slide mechanism. Smooth action and high side stability through precision slide. Ball spacers made of noise-absorbing plastic with hardened steel balls.


 3/4" Installation Width - 3" Height. Tested Weight Capacity 500 [email protected] 10,000 Cycles - 325 lbs. @ 75,000 Cycles. Cabinet member requires #10 Flat head countersunk screw. Drawer member requires #10 pan head screw. Screw length will vary depending on application. Use all screw holes to acheive full load rating.


PRICE IS PER PAIR. Screws not included.

    18 inch slides work great
    I installed these on an 80 inch wide, sliding fire place hearth. The aluminum frame work weighs about 80 lbs, the sides are tiled with a marble slab top. I can stand on the front edge with slides fully extended with less than an eighth inch deflection. They work great.
