Undermount Drawer Slide Built for Precision Alignment and Full-Access Travel

This is the right-hand member of Hettich's Quadro V6 21 inch undermount slide — a concealed, full-extension runner with integrated soft-close, ball-bearing carriage, and 4D adjustment capability, rated 90 lb per pair for drawer boxes with 1/2 to 5/8 inch sides.

Key Features

• Right-hand member, bulk single: pairs with the matching left-hand Quadro V6 slide to complete one working set — order one of each per drawer.
• Full extension: the entire drawer travels out to the cabinet face, putting every inch of the 21 inch box within reach.
• Integrated soft-close: a built-in damper catches the drawer near the end of travel and settles it shut without slamming.
• 4D adjustment: the Quadro V6 system supports height, side, tilt, and depth fine-tuning through its locking devices, letting installers true the front after hanging.
• Ball-bearing carriage: hardened steel bearings run in formed raceways for a smooth, controlled pull under load throughout the drawer's service life.
• Suits face-frame and frameless cabinets: installs in both construction types with the correct series-specific rear hardware.

Where This Slide Fits the Job

A 21 inch full-extension undermount covers the most common kitchen base-cabinet drawer depth — pots-and-pans drawers, utensil banks, and deep pantry drawers that need rear-corner access. The 90 lb per-pair rating handles a fully loaded kitchen drawer without strain, and the full-extension travel means nothing stays buried at the back. Because the slide is concealed beneath the box, the drawer interior reads as clean wood with no visible hardware. Production shops running Hettich as their undermount standard will stock this right-hand member alongside the left-hand counterpart and pull pairs from each bin per drawer.

Construction and Finish

The Quadro V6 body is formed steel with a zinc finish, a practical surface that resists corrosion through years of indoor kitchen service and stays out of sight beneath the drawer box. The ball-bearing carriage is the key structural difference from roller-based undermounts: hardened steel balls in formed raceways deliver a consistent, load-bearing pull across the full 21 inch travel, even as drawer contents shift. The 4 mm side clearance per side is tighter than the 3/16 inch (approximately 4.8 mm) typical of roller-based systems, so box-width calculations should use the Hettich Quadro V6 specification directly.

Who Should Specify This Slide

Cabinet shops building 21 inch drawer boxes on 1/2 to 5/8 inch material — dovetailed maple, doweled Baltic birch, or CNC-cut plywood — and specifying Hettich as their undermount platform will find the Quadro V6 the right-hand runner for those boxes. Designers calling out Hettich on a kitchen project get full-extension travel and post-install 4D adjustment, which shortens the punch-list on jobs with numerous drawer fronts to align. In face-frame cabinets, pair this slide with Quadro V6 series rear mounting brackets; in frameless work it mounts directly to the cabinet side. Both locking devices and rear brackets are series-specific Quadro V6 parts and do not interchange with other undermount brands or series.

The Right Member for the Right Drawer

Pair this right-hand Quadro V6 slide with its left-hand counterpart, build the box to the Hettich specification, add the series locking devices and any required rear brackets, and the 21 inch drawer goes in straight and stays aligned.
