Undermount Drawer Slide For Frameless Cabinets With Precision Ball-Bearing Travel

This is the left-hand member of Hettich's Quadro V6 concealed undermount system in the 500mm nominal length — a full-extension, soft-close runner built on ball bearings and rated 90 lb per pair, sized for drawer boxes with 1/2 to 5/8 inch sides in frameless cabinet construction. Order the matching right-hand member alongside this one to make a complete working pair.

Key Features

• Ball-bearing carriage delivers a smooth, precise pull through the full travel range, even under load.
• Full extension brings the entire drawer box out to the cabinet face, so the back of the drawer is reachable without digging.
• Integrated soft-close catches the drawer near the end of travel and settles it shut silently, without a slam.
• 90 lb capacity per pair handles loaded kitchen, bath, and utility drawers within the standard residential range.
• Left-hand orientation — this is one member of the pair; the right-hand slide must be ordered separately to complete the set.
• Frameless cabinet fit with a 500mm nominal length and a minimum installation depth of 20-11/16 inches.

Where This Slide Does Its Work

The 500mm nominal length — approximately 19-11/16 inches closed — suits the deeper drawer runs common in modern frameless kitchen and bath cabinetry: pots-and-pans drawers, wide utensil drawers, and linen pulls where rear access matters. Full extension means the entire box clears the cabinet opening, so nothing stays buried at the back. The ball-bearing carriage keeps travel smooth whether the drawer is empty or loaded close to the 90 lb per pair rating. Cabinet minimum installation depth is 20-11/16 inches, so confirm the interior depth before specifying this length.

Construction and Finish

The Quadro V6 runner is steel with a zinc finish — a functional indoor finish that resists corrosion through years of service without needing to be seen. Because the slide mounts concealed beneath the drawer box, the zinc finish is hidden in normal use. The ball-bearing system is the key structural differentiator from roller-bearing undermounts: steel balls in precision raceways carry the load more rigidly and with less deflection at the far end of travel, which matters on longer and heavier draws. The integrated soft-close damper is built into the runner body, so no separate add-on is needed at install.

Who Orders This Slide

Cabinet shops running frameless production are the core buyer here: the Quadro V6 drops straight onto a frameless box side, and the 500mm length maps to the deeper drawer boxes typical of full-height base cabinets. Designers specifying handle-less fronts appreciate that soft-close is already built in, with no extra components to coordinate. Renovation contractors retrofitting frameless European-style cabinets will find this length covers the most common deep-drawer situation. The 1/2 to 5/8 inch side-thickness range suits dovetailed maple, doweled plywood, and most shop-built drawer box stock. Builders working in face-frame construction should select the face-frame version of this line instead, as this SKU is rated and configured for frameless installation only.

The Right Runner Keeps the Drawer Moving

Match the left-hand slide with its right-hand pair, build the drawer box to Hettich's specification for the Quadro V6 in the 500mm length, and this concealed runner delivers full-extension ball-bearing travel with integrated soft-close — quietly, in a frameless cabinet, for the long run.
