Ball Bearing Undermount Slide For Precise, Silent Drawer Action in Frameless Cabinets

The Hettich Quadro V6 400mm undermount slide is the left-hand member of a concealed, full-extension runner system built around steel ball bearings, an integrated soft-close damper, and a 90 lb per pair load rating. Designed for frameless cabinet construction, it pairs with the matching right-hand runner to carry drawer boxes with 1/2 to 5/8 inch sides on a 400mm nominal length.

Key Features

• Left-hand single: This SKU is the left-hand cabinet member only — pair it with the right-hand Quadro V6 400mm runner to complete one working set.
• Full extension: The drawer travels the full nominal length, bringing the entire box to the cabinet face so rear contents are fully accessible.
• Integrated soft-close: A built-in damper catches the drawer near the end of travel and settles it shut silently without slamming.
• Ball bearing carriage: Hardened steel ball bearings run in formed raceways for smooth, consistent travel under load.
• 90 lb capacity per pair: Sized for loaded kitchen, bath, and utility drawers in residential and light commercial work.
• Frameless cabinet fit: Mounts directly to the flat interior side panel — no face-frame adapter or rear bracket is required for frameless construction.

Where This Slide Belongs in a Build

The 400mm Quadro V6 is the right length for drawers in the 15 to 16 inch depth range — a common size for upper utility drawers, bath vanity drawers, and the secondary tiers in kitchen base cabinets. At full extension, the complete drawer box clears the cabinet opening, which matters when reaching into the back of a small drawer where every inch of access counts. The 90 lb per pair rating handles everyday kitchen and bath loads without headroom to spare on very heavy applications, so it is well matched to standard drawer contents rather than dense pantry pull-outs.

Construction and Finish

The Quadro V6 runner is built from steel with a zinc finish that protects against corrosion through years of indoor service. Ball bearing construction is the differentiating detail at this tier: where roller-based undermounts use molded nylon wheels, the Quadro V6 runs on hardened steel balls in full-length raceways, which delivers more consistent travel feel and holds up better under sustained load cycling. The integrated soft-close mechanism is part of the runner body — no separate damper clip to install or lose.

Who Orders This Runner and Why

Cabinet shops running frameless European-style production are the primary buyer here. A 400mm ball bearing soft-close runner at 90 lb fits the spec for most residential drawer programs without overbuilding. Because this line sells as individual handed members, shops can stock left and right singles by the case and pull what each job needs rather than managing paired sets. Designers specifying a handle-less kitchen will find the full-extension travel and soft-close combination covers the baseline expectation for that application. Installers finishing a frameless build get a runner that screws directly to the side panel on standard system-hole spacing with no additional mounting hardware required for frameless work.

Get the Right Runner for the Job

Match the 400mm left-hand Quadro V6 with its right-hand counterpart, build the drawer box to the Hettich specification for this series, and this concealed runner delivers consistent, silent full-extension travel on every cycle.
