21-5/8 Inch Undermount Drawer Slide for Deep Kitchen and Cabinet Drawers

The Hettich Quadro V6 is a 550mm (21-5/8 inch nominal) full-extension, soft-close ball-bearing undermount drawer slide engineered for frameless cabinetry. This listing is for the right-hand cabinet member, sold as a single unit. Pair it with the matching left-hand member and the appropriate drawer members to complete the drawer installation.

Key Features

• Full extension brings the entire drawer out to the cabinet face, giving you access to the back of the box without reaching in.
• Integrated soft-close catches the drawer near the end of travel and settles it shut quietly — no slam, no bounce.
• Ball bearing mechanism delivers smooth, consistent pull across the full 550mm travel under load.
• 90 lb weight capacity handles heavily loaded kitchen, pantry, and utility drawers with confidence.
• Right-hand orientation — this is the cabinet-side member for the right side of the drawer; handedness is built into the Quadro V6 design.
• Zinc finish on steel gives the slide lasting corrosion resistance through daily indoor use.

Where a 550mm Slide Earns Its Place

At 550mm (21-5/8 inch nominal), this slide length suits deeper cabinet runs — think base cabinets in a standard 24-inch-deep kitchen, tall pantry pull-outs, or deep utility drawers where the box runs close to the full interior depth. The minimum installation depth is 22-5/8 inches, so verify your cabinet's interior depth clears that before ordering. Full extension means the entire drawer box clears the cabinet opening, so nothing stays hidden in the back — a meaningful advantage in a pots-and-pans drawer or a deep drawer stacked with supplies.

The soft-close mechanism earns its keep in high-traffic rooms. Heavy drawers loaded with dishes or hardware tend to land hard; the damper in the Quadro V6 absorbs that energy and eases the drawer home on every cycle. The result is quieter cabinetry and less wear on the box and front over time.

Build and Finish Details

The Quadro V6 is built from steel and finished in zinc, the durable, corrosion-resistant standard for indoor drawer hardware. The ball-bearing system runs on formed steel raceways for consistent travel over years of use — a practical choice for kitchen environments where drawers open dozens of times a day. The slide is designed for drawer sides between 1/2 inch and 5/8 inch thick; confirm your box thickness falls in that range before building or ordering. The Quadro V6 is engineered for frameless (European-style) cabinetry, where the slide mounts directly to the cabinet side panel.

Who This Slide Suits

Cabinet shops running frameless kitchen and bath programs will find the Quadro V6 fits naturally into production workflows — the soft-close function is built in rather than added on, which keeps the component count down per drawer. Designers specifying residential kitchens get the full-extension access and quiet close that clients expect in premium cabinetry, at a practical price point for volume builds. Contractors replacing slides in existing frameless cabinets can match the 550mm length to the original drawer depth and swap in without rebuilding the box, as long as the drawer sides are in the 1/2 to 5/8 inch range and the cabinet depth clears 22-5/8 inches.

The Right Slide, Ready for Deep Drawers

The Quadro V6 at 550mm covers the depth that most standard kitchen base cabinets demand — full extension, integrated soft-close, and 90 lb capacity in a single ball-bearing undermount that installs clean in any frameless build.
