Zinc Ball-Bearing Undermount Slide For Frameless Cabinet Builds

The Hettich Quadro V6 in the 550mm (21-5/8 inch) nominal length is a right-hand, full-extension, soft-close undermount drawer slide built for frameless cabinetry. It runs on ball bearings, carries 90 lb per pair, and mounts concealed beneath the drawer box so the hardware stays hidden when the drawer is open.

Key Features

• Full extension brings the entire drawer box out to the cabinet face, putting the back of the drawer within reach.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• Ball-bearing carriage delivers a smooth, precise pull under load across the full 550mm travel range.
• 90 lb weight capacity per pair handles heavily loaded kitchen and utility drawers without strain.
• Right-hand orientation — this is a single slide; pair it with the matching left-hand Quadro V6 550mm slide to complete one drawer installation.
• Frameless cabinet construction — the slide mounts directly to the flat interior cabinet side panel.

Where This Slide Fits the Job

The 550mm Quadro V6 right-hand slide is the right call for frameless production cabinetry where full rear access matters. Kitchen base drawers holding pots, pans, or pantry staples benefit from the full-extension travel — the whole box clears the cabinet opening so nothing stays buried at the back. The 90 lb per pair capacity covers realistic drawer loads in residential and light commercial kitchens without stepping up to a heavier-duty class. Because the slide is concealed beneath the box, it suits modern frameless builds where a clean interior look is part of the design intent.

The 550mm nominal length requires a minimum installation depth of 22-5/8 inches in the cabinet. Confirm your cabinet interior is deep enough before ordering this length.

Steel, Zinc Finish, and Ball-Bearing Construction

The Quadro V6 is built from steel with a zinc finish — a functional, corrosion-resistant coating suited to the indoor environments this slide is designed for. Ball bearings running in formed steel raceways distinguish it from roller-bearing undermounts in the same category: the bearing system delivers a tighter, more consistent feel under load and maintains that feel across the drawer's service life. Because the slide rides beneath the box, the zinc finish is largely out of sight in use, so it is working protection rather than a decorative element.

Who Orders This Slide and How

Cabinet shops running frameless production lines are the primary buyer for bulk Quadro V6 singles. Ordering by handedness — separate left and right slides — gives a shop precise control over stock, which matters when building runs of drawers at volume. Designers specifying premium concealed hardware for frameless projects will find the Quadro V6 sits in the full-extension, soft-close tier that meets most residential and light-commercial specifications. Contractors installing or replacing undermount slides in existing frameless casework can match this slide to the Hettich Quadro V6 series already in the cabinet.

The drawer box must be built to Hettich's published specification for the Quadro V6 series — correct nominal length, box-width formula for the side clearance, bottom recess, and rear notch. Quadro V6 locking devices and rear brackets are series-specific and do not interchange with other brands or Hettich series. Confirm which locking device version your installation requires before completing the order.

The Right Slide, Ready to Work

Match the 550mm right-hand Quadro V6 to its left-hand partner, build the box to Hettich's spec, and this concealed slide delivers full extension and quiet soft-close in a frameless cabinet that's built to last.
