This product has been discontinued by the manufacturer. No more are available.

The Hettich KA3320 36″ 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. Ball bearing spacers are made of noise-absorbing plastic with hardened steel ball bearings. 

The runner and ball race form a single non-detachable unit. Smooth action and high side stability through precision slide. The 3 foot 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 3 feet of travel to its fully extended 6 foot 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.


This 36″ slide has a 3/4″ installation Width and is 3″ in height. The drawer member and cabinet member requires #10 pan head screw. Screw length will vary depending on application. Use all screw holes to achieve full load rating.


PRICE IS PER PAIR. Screws not included.


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

      Rock Solid Drawer Slides
      These worked perfectly. I always feel you need to over build things that will take abuse from users that don’t take into consideration how fragile a drawer might be.

      Makes a Great Pocket Door Track
      Used these as sliding door track. They work great. Keeps the door from swinging and functions just like you would expect. I used one on the bottom and a regular door track on the top.

      If You Need Heavy Duty Slides
      If you need heavy duty Drawer Slides, these are the ones. Have had them in use for 2 years on a drawer that is 4′ wide and ends up with all of the kitchen small appliances and its still holding the weight. Use good screws.

      Outstanding Quality
      I ordered these slides to build a slideout tray for a motor home storage bay. They are very heavy duty, excellent quality and worked like a charm. I am very pleased with how well they worked.

    5. Jack Green (verified owner)

      Received fast and was packaged really well. Would recommend!

      Great product / good service /
      I ordered 2 sets of 60" glides and 4 sets of 36" glides for my van work space. Love the products. My initial enclosure for one of the 60" glides was slightly snug causing drag. I asked tech support a question and they pointed me in the right direction. I would love them if they had a quick connect but totally understand why that can’t happen in such a heavy duty product. Would recommend both the seller and the product. Very happy with them

      These are serious drawer glides
      I used them under the bench seat of a motorhome very successfully. These are very heavy duty weight bearing glides that are of a top quality construction. I would high recommend them.

      Great product
      I bought my drawer glides for under the staircase drawers, these are huge drawers and heavy but you would never know it by how easy they slide in and out. When it came time to paint the staircase, I actually had to sit in the drawers to do the detail work. All I can say is this product is everything it was advertised to be and more. Easy to purchase and great customer service!

      Great Service from OVIS
      Product seems good, service from OVIS was great!

      Great 👍
      We had an unusual application for these slides. I replaced the fold up bed 🛏 in the back of our RV with a fabricated box and sliding drawer arrangement. The drawer would slide in when the RV slide was retracted. When the RV slide was extended, we would pull out the Drawer to make a queen size bed. It works perfectly. I did attach some hinges vertically to the side of the drawer to provide additional support when the bed was fully extended, as recommended by your staff. The hinges would fold away from the drawer sides when we wanted to push the drawer in for travel or to use the bench seat under the bed

      36" Full Extension Drawer Slide
      I used this product to support a large pull-out Pantry which is 3' deep x 5' high and 15" wide. Plywood alone is about 100 lbs. It takes careful preparation to ensure all mounting is solid and exact. My project turned out 100%. I would highly recommend this product.

      Excellent Quality Slides
      They came in due time and are extremely heavy duty. Doing a great job.

    15. Richard (verified owner)

      Excellent Slides
      I was making use of space under the stairs for shoes/boots and such and needed 36" heavy duty drawer slides. After shopping around, I decided to go with these from OVIS. They worked perfectly for my application and installed easily! They seem to be very sturdy, roll open easily, and should hold up for years! Great product.

    16. Paul (verified owner)

      Exceptional product
      Easy to install, high weight capacity and smooth operation. First time installing something this long and I will not hesitate to use this product again.

    17. Bill in Tustin (verified owner)

      I now have 3 of these.
      I purchased these at different times but all have worked out great. I am a woodworker with a 100# thickness planner and put wood through it. To use it, I just pull the planer out of its cabinet hook up the dust collection and start feeding boards through. EXTREMELY solid, no wiggle, no problems. Best setup for my planer yet.

      36" Drawer Slides, Heavy Duty, Full Extension
      High quality with excellent ease of operation!

    19. Matt F (verified owner)

      Exactly what i needed
      They match the description perfectly and are fantastic in my pantry. I'd buy them again, but Ovis accidentally doubled my order upon shipping, so i don't have to. Five stars all around!

    20. Carr Tom (verified owner)

      Hvy duty as advertised and well enough made. I’d do it again.

    21. Joel (verified owner)

      We mount generators and air compressors on the slide outs and they work excellent.
