Left-Hand Ball-Bearing Undermount Slide Built for Frameless Cabinetry

This is the left-hand member of Hettich's Quadro V6 undermount drawer slide system in the 320mm nominal length — a concealed, full-extension runner with integrated soft-close, ball-bearing travel, and a 90 lb per pair capacity, designed for frameless cabinets with drawer sides from 1/2 to 5/8 inch thick.

Key Features

• Left-hand orientation — this single member pairs with its right-hand counterpart to form one complete working set per drawer.
• Full extension — the drawer travels the full nominal length, bringing the entire box out to the cabinet face for complete rear access.
• Integrated soft-close — a damper catches the drawer near the end of travel and settles it shut quietly, without a separate add-on component.
• Ball-bearing carriage — hardened steel ball bearings run in formed steel raceways for smooth, precise travel under load.
• 90 lb rated capacity per pair — sized for loaded kitchen, bath, and utility drawers.
• Steel construction with zinc finish — a functional corrosion-resistant finish suited to years of indoor service.

Where This Slide Fits

The Quadro V6 320mm runner is sized for frameless cabinetry — it mounts directly to the flat cabinet side panel without a face frame in the way. At roughly 12-9/16 inches (320mm) nominal length, it suits shallow base drawers, bathroom vanity drawers, and compact utility cabinets where a longer slide would not clear the interior. The minimum installation depth is 13-9/16 inches, so confirm that your cabinet's interior depth meets or exceeds that before ordering. The slide is built for drawer boxes with 1/2 to 5/8 inch sides — the standard thickness range for dovetailed hardwood and doweled plywood construction.

Construction and Finish

Steel members with a zinc finish protect the slide through years of indoor cycling. Ball bearings — rather than nylon rollers — give the Quadro V6 a more precise, consistent pull under load and over time. The soft-close damper is integrated into the slide body, so there are no separate damper cartridges to source or replace. Because the slide mounts beneath the drawer box and stays hidden when the drawer is open, the zinc finish serves a protective function rather than a decorative one.

Who Orders This Slide

Production cabinet shops running frameless lines reach for the Quadro V6 when a project calls for concealed slides with ball-bearing precision and integrated soft-close in a compact length. Residential installers fitting bathroom vanities or kitchen island drawers with shallow boxes find the 320mm size fills the gap between the shortest undermounts and a standard 18-inch runner. Because these are sold as single handed members, shops can stock lefts and rights by the case and pull them as needed rather than unwrapping pairs for every drawer.

Build the Right Drawer Box, Get the Right Result

Match the Quadro V6 to a drawer box built to Hettich's specification for this series — correct nominal length, box-width formula for the side clearance, bottom recess, rear notch, and locking-device drilling — and the concealed runner delivers full-extension ball-bearing travel with a quiet, damped close on every cycle.
