Concealed Undermount Slide For Frameless Cabinetry With Precise Ball-Bearing Travel

This is the left-hand member of the Hettich Quadro V6 undermount system in the 300mm nominal length — a fully concealed, full-extension soft-close runner built on steel ball bearings, rated 90 lb per pair, and sized for drawer sides from 1/2 to 5/8 inch. It installs in frameless cabinets and ships as a single handed slide.

Key Features

• Left-hand orientation: This is one member of a pair — pair it with the matching right-hand Quadro V6 300mm slide to complete a working drawer installation.
• Full extension: The drawer box travels the full nominal length, bringing the entire interior out to the cabinet face.
• Integrated soft-close: A damper catches the drawer near the end of travel and settles it shut without slamming.
• Ball-bearing carriage: Steel ball bearings in full-length raceways deliver smooth, precise travel under load across years of daily use.
• 90 lb capacity per pair: Sized for loaded kitchen and bath drawers within the Quadro V6's standard rating.
• Frameless cabinet design: Mounts directly to the flat cabinet side panel, no face-frame adaptation needed.

Where This Slide Fits the Job

The 300mm nominal length targets shallower drawers — spice pull-outs, sink-base trays, and compact vanity drawers where the cabinet's interior depth is limited. The minimum installation depth is 12-3/4 inches, so the slide fits cabinets that a longer runner cannot. At full extension, the entire drawer box clears the opening and the back of the drawer is reachable without reaching into the cabinet. That matters in sink bases and narrow upper-cabinet drawers where depth is already at a premium. For shops running frameless production lines, the Quadro V6 mounts directly on the cabinet side panel without additional face-frame hardware — a straight drop-in on the common 32mm system grid.

Construction and Finish

The Quadro V6 runner is steel with a zinc finish — a functional, corrosion-resistant surface that stands up to indoor service without calling attention to itself beneath the drawer box. The ball-bearing bearing system is what separates this runner from roller-based economy slides: hardened steel balls in formed raceways carry the load smoothly and maintain consistent travel feel over time. The soft-close damper is integrated into the slide body, so there are no separate damper clips to lose or replace. The zinc finish keeps the concealed runner protected through long production runs and daily kitchen cycles alike.

Who Orders This Runner

Production cabinet shops specify the Quadro V6 for frameless lines where a reliable, consistent concealed runner is more important than the widest possible adjustment range. A 300mm slide in particular suits shops building shallow drawers — sink-base trays, compact bathroom vanities, and appliance garage pull-outs — alongside their standard 18 and 21 inch drawer runs. Designers specifying frameless contemporary kitchens choose this runner where a clean, hardware-free drawer interior is part of the design intent. Homeowners sourcing replacements for an existing Quadro V6 installation should confirm the series version (V6 specifically) and the nominal length before ordering, since Quadro brackets and clips are version-specific and do not interchange across series generations.

The Right Left-Hand Runner for a Clean Frameless Build

Match this left-hand Quadro V6 300mm runner with its right-hand mate, build the drawer box to Hettich's specification, and the 300mm concealed slide delivers full extension and silent soft-close in frameless cabinetry where shorter depth is part of the design.
