Hettich Quadro V6 21" Soft-Close Full Extension Undermount Drawer Slides, Ball Bearing Left hand Zinc - 9304280

Left-Hand Soft-Close Undermount Slide for Face-Frame and Frameless Cabinetry

The Hettich Quadro V6 21 inch undermount drawer slide is the left-hand member of a concealed, full-extension runner system — ball bearing, soft-close, rated 90 lb per pair, and built for drawer boxes with 1/2 to 5/8 inch sides. Order the matching right-hand slide to complete one working pair.

Key Features

• Full extension brings the entire 21 inch drawer out to the cabinet face so nothing stays hidden at the back.
• Integrated soft-close catches the drawer near the end of travel and settles it silently shut without slamming.
• 90 lb weight capacity per pair handles loaded kitchen and bath drawers with room to spare.
• Ball-bearing carriage rolls on hardened steel bearings for a smooth, precise pull under load.
• Suits face-frame and frameless cabinets — one slide handles both construction types with the correct series hardware.
• 4 mm side clearance keeps the concealed profile tight while leaving room for a properly sized drawer box.

Where This Slide Fits the Job

A 21 inch undermount is the right length for standard base cabinets built to a 21 or 22 inch interior depth — deep enough for a full kitchen drawer stack without dead space at the rear. Full extension means every inch of that depth is reachable when the drawer is open, which matters most in drawers storing deep pots, utensils, or filing. The integrated soft-close eliminates the rattle and impact of a hard close, which is why this spec is now standard in residential kitchens and increasingly expected in bath vanities and furniture drawers. The 90 lb per pair rating covers most loaded residential applications, from a heavy cutlery tray to a double layer of stacked pots.

Build and Finish

The Quadro V6 member is steel with a zinc finish — a functional, corrosion-resistant surface suited to indoor service. Because the slide is concealed entirely beneath the drawer box, the finish does not factor into the cabinet's visible aesthetic; what matters is durability through years of daily cycling. Ball bearings running in full-length steel raceways deliver consistent travel even as the drawer loads and unloads over time. The 4 mm side clearance is engineered into the Quadro V6 profile, so box sizing follows Hettich's specification for this series rather than a generic 1/2 inch per side rule.

Who Orders This Slide

Cabinet shops running production builds stock Quadro V6 left and right members by the case and pair them at assembly. The slide suits both face-frame and frameless construction, which means one product covers a mixed shop's output without splitting inventory by cabinet type. Custom builders and installers specifying a soft-close, ball-bearing undermount in the 21 inch length will find the Quadro V6 a direct match for premium residential work. For 3/4 inch drawer sides, a different series model is required — this version is sized for boxes with 1/2 to 5/8 inch material.

The Right Slide for Drawers That Work Every Day

Match the 21 inch length to your cabinet depth, build the box to the Hettich spec, add the series-correct locking devices and any brackets your construction requires, and the Quadro V6 delivers full-extension, soft-close performance that holds up through years of daily use.
