The Hettich KA3320 44″ 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 44 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 44 inches of travel to its fully extended 80 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: 280 lbs. @ 10,000 cycles – 183 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.

    1 review for 44″ Drawer Slides, Heavy Duty, Full Extension

    1. John McCaffery III (verified owner)

      Exactly what I ordered!
      Excellent customer service, called twice with questions. 44" sliders arrived and HEAVY! Packed to the max to avoid damage. I'm building a slide out for my off road trailer M8-A1 mule. Prices were over $500 for a ready made. I will never need the (500) capacity. But rest assured these will do the job. Mounted to 2x4s and angle iron on the inside. All the holes lined up. Highly recommended!
