Hettich Logo

The Hettich KA3320 48" 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 48 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 48 inches of travel to its fully extended 96 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.


This 48" slide has a 3/4" installation Width and is 3" in height. The recommended fastener is a #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.

    Slide for Concealed Drawer Gun Table
    I have purchased 7 sets of the 48 inch slides to use in Concealed Drawer gun tables. They are fabulous. Each customer is amazed when the drawer is opened to the fully extended position and it is still as solid as a rock. I have purchased many times from ovisonline.com and the service has been stellar every time. Wonderful people to deal with.

    I build a slide-out kitchen in the back of my van with these. They are strong, well-built, and exactly what I needed.
