Concealed Undermount Slide For Frameless Cabinets With 380mm Drawer Boxes

This is the left-hand slide of Hettich's Quadro V6 undermount system in the 380mm nominal length — a full-extension, ball-bearing concealed runner with integrated soft-close, rated 90 lb per pair and built for frameless cabinets with 1/2 to 5/8 inch drawer sides. It sells as a single left-hand member; pair it with the matching right-hand Quadro V6 380mm slide to complete one working set.

Key Features

• Left-hand single — order one left and one right Quadro V6 380mm slide to make a working pair for one drawer.
• Full extension — the drawer box travels out to the cabinet face, putting the entire interior within reach.
• Integrated soft-close — a damper catches the drawer near the end of travel and settles it shut without slamming.
• 90 lb capacity per pair — rated for loaded kitchen, bath, and utility drawers.
• Ball-bearing carriage — hardened steel bearings in formed raceways deliver a smooth, precise pull under load.
• Frameless cabinet fit — mounts directly to the flat interior panel of a frameless (European-style) cabinet box.

Matching the Right Drawer Box and Cabinet

The Quadro V6 is engineered for frameless cabinet construction, where the slide screws directly to the interior side panel. It is not the face-frame version of the Quadro line — if your project uses face-frame cabinets, confirm that the correct face-frame configuration is specified before ordering.

The 380mm nominal length (approximately 14-15/16 inches closed) requires a minimum installation depth of 15-15/16 inches inside the cabinet. Build the drawer box to the Hettich specification for this series: nominal 380mm length, the correct box-width formula for the side-clearance, bottom recess, rear notch, and the drilling pattern for Quadro V6 front locking devices. An off-spec box will not seat correctly on the runners.

Drawer sides must fall between 1/2 inch (12.7mm) and 5/8 inch (16mm). This is the standard 16mm version of the Quadro V6 — it is not interchangeable with versions engineered for 3/4 inch (19mm) material.

Construction and Finish

The Quadro V6 members are steel with a zinc finish, a functional corrosion-resistant coating suited to years of indoor service. Ball bearings run in full-length formed raceways, keeping travel smooth and consistent even when the drawer carries close to its rated load. Because the slide mounts beneath and concealed by the drawer box, the finish is a practical interior choice rather than a visible decorative one.

Front locking devices for the Quadro V6 are series-specific Hettich parts — Quadro clips and brackets do not interchange with runners from other brands or with other Hettich series. Confirm that locking devices and any rear mounting components in your order are Quadro V6 versions.

Who Reaches for the Quadro V6 380mm

This slide length fits the shorter drawer boxes common in base-cabinet roll-outs, bathroom vanity drawers, and kitchen accessory drawers where the cabinet is not full depth. Production shops running frameless lines that need a reliable, full-extension concealed runner with soft-close and a straightforward ball-bearing feel will find the Quadro V6 at home in that workflow. Designers specifying handle-less modern kitchens get the clean concealed look without giving up rear drawer access. At 90 lb per pair, it handles a heavily loaded spice drawer or a utensil pull-out without strain.
