Hettich Logo

The Hettich KA3320 22″ drawer slides are a heavy duty, telescoping, precision, full extension drawer slides for high loads, up to 500 lb. capacity, with cushioned in and out stops. Chromated steel.


The runner and ball race form a single non-detachable unit. Smooth action and high side stability through precision slide. Ball spacers made of noise-absorbing plastic with hardened steel balls. The 22 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 22 inches of travel to its fully extended 44 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.


3/4″ Installation Width – 3″ Height. Tested Weight Capacity: 430 lbs.@ 10,000 Cycles – 280 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.


Manufactured by Hettich America, in Buford, GA, USA.

      Good Product, Good Price
      These slides were used to replace the OE slides. I purchased them for less than 50% of the cost of the OE slides and they are doing just fine.

      Heavy Duty!
      Using these and the 16” for a set of customer storage and display units. They are very ridged which was required as the drawers are 45” x 23” and 17” . Good value and I enjoyed working with the folks at Ovis.
