Ball Bearing Precision and a Frameless-Ready Fit

The Hettich Quadro V6 520mm undermount drawer slide is a left-hand, full-extension concealed runner with integrated soft-close, built for frameless cabinets and drawer boxes with 1/2 to 5/8 inch sides. Sold as a single left-hand member, it pairs with the matching right-hand Quadro V6 slide to make one working set.

Key Features

• Ball-bearing carriage delivers smooth, precise travel across the full length of the slide under load.
• Full extension brings the entire drawer box out to the cabinet face, putting rear contents within easy reach.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• Left-hand orientation means this single member is the dedicated left side of a Quadro V6 pair — handedness is built into the design.
• 90 lb capacity per pair handles loaded kitchen, bath, and utility drawers without strain.
• Steel construction with zinc finish provides reliable indoor corrosion resistance concealed beneath the drawer box.

Where This Slide Earns Its Keep

Full-extension, soft-close undermounts are most at home in kitchen and bath drawers where rear access matters — the back of a spice drawer, a deep utensil pullout, or a linen drawer in a bath vanity. At 520mm (approximately 20-15/32 inches nominal length), this slide suits standard-depth base and vanity cabinets. The 90 lb per-pair rating keeps loaded pots-and-pans drawers well within spec and covers the full range of typical residential drawer applications. Because the slide is fully concealed beneath the box, the finished interior shows only wood — no hardware visible from above or the side.

Construction and Finish

Steel ball-bearing members running in zinc-finished steel tracks give the Quadro V6 its characteristically smooth, quiet pull. Ball bearings — rather than nylon rollers — maintain consistent feel under heavier loads and across years of cycling. The zinc finish protects the steel members through normal indoor service life. Since the runners mount beneath the drawer box and stay hidden when the drawer is open, the finish is functional rather than decorative. This is a frameless-cabinet slide: it mounts directly to the flat interior side panel, with no face-frame rear bracket required.

Who This Slide Suits

Production cabinet shops running frameless, European-style cabinetry are the natural fit — particularly those building boxes from 1/2 to 5/8 inch material on a consistent specification. The 520mm length works in standard 21-inch-depth base cabinets, which require a minimum installation depth of 21-15/32 inches per the Quadro V6 spec. Designers specifying premium concealed slides for residential kitchens and baths get full-extension access and quiet soft-close in a single compact runner. Contractors replacing worn undermount runners in existing frameless casework will find the Quadro V6 a direct-fit upgrade, provided the drawer box was built to the Hettich specification for drawer side thickness and rear notching.

Precise Movement, Clean Results

When the drawer closes silently and the cabinet interior shows nothing but wood, the Hettich Quadro V6 has done its job — order the left and right members together, build the box to spec, and install with confidence.
