Hettich Quadro V6 18" Soft-Close Full Extension 90 lb Undermount Drawer Slide, Zinc,

Ball Bearing Precision And Dual-Cabinet Fit

The Hettich Quadro V6 is an 18 inch full-extension undermount drawer slide with integrated soft-close, built on a ball-bearing carriage and rated 90 lb per pair. It runs concealed beneath the drawer box in both face-frame and frameless cabinets, making it a versatile choice across construction styles.

Key Features

• Ball-bearing carriage delivers a smooth, precise pull under load across the full 18 inch travel.
• Full extension brings the entire drawer box out to the cabinet face, so rear contents are fully reachable.
• Integrated soft-close catches the drawer near the end of travel and settles it shut quietly.
• 90 lb weight capacity per pair handles loaded kitchen and bath drawers without strain.
• Face-frame and frameless compatibility covers both traditional American and modern European cabinet constructions.
• Steel construction with zinc finish provides lasting indoor corrosion resistance in a concealed application.

Where the Quadro V6 Earns Its Keep

The 18 inch length suits standard kitchen base drawers, bathroom vanity boxes, and mid-depth utility drawers. Full extension means the back of the drawer comes all the way to the cabinet face, which matters in spice drawers, utensil trays, and any box where reaching the rear contents is part of the design intent. The 90 lb per-pair rating covers a fully loaded drawer without approaching the slide's limit, leaving meaningful headroom for everyday use. In face-frame cabinets, the rear of the slide requires the matching Quadro-specific rear mounting brackets, which are sold separately — these are version-specific hardware and do not interchange with brackets from other undermount lines. In frameless cabinets, the slide mounts directly to the cabinet side panel.

Build and Finish

Steel members and a zinc finish are the standard for a functional, indoor undermount slide that spends its service life hidden beneath the drawer box. The ball-bearing carriage is the meaningful distinction here: where roller-bearing slides rely on nylon wheels running in formed tracks, the Quadro V6 uses hardened steel balls in retainers that roll between steel raceways, giving a more precise feel and consistent resistance across the slide's travel. The zinc plating handles normal indoor humidity without issue. This is not a finish chosen for appearance — it is chosen for protection in a concealed install.

Who Should Specify This Slide

Cabinet shops running a mix of face-frame and frameless production benefit from stocking one slide that covers both constructions. The Quadro V6 at 18 inches is the right pick for drawer boxes built to 1/2 to 5/8 inch side thickness — dovetailed maple boxes, doweled plywood boxes, and CNC-cut drawer parts all fall in that range. Designers specifying premium residential kitchens get the soft-close and full-extension behavior their clients expect from a concealed runner. Contractors installing replacement drawers in existing face-frame kitchens can use the same slide without switching products. The drawer box must be built to Hettich's published specification for the Quadro V6 series — correct nominal length, box-width formula, bottom recess, rear notch, and locking-device drilling. An off-spec box will not seat correctly on the runners.

A Concealed Runner Built for the Full Range of Cabinet Work

The Quadro V6 at 18 inches pairs ball-bearing precision with soft-close damping and covers face-frame and frameless construction in one slide, so a single stock position handles more of the jobs that come through the shop.
