This is the right-hand member of Hettich's Quadro V6 concealed undermount system in the 520mm length — a full-extension, soft-close runner on ball bearings, rated 66 lb per pair, built for frameless cabinets and drawer boxes with 1/2 to 5/8 inch sides.
The 520mm length suits drawers in the 20 to 21 inch nominal range — a common depth for base kitchen cabinets, bath vanity drawers, and built-in storage in frameless casework. Full extension makes the entire drawer interior reachable, which matters in a kitchen spice pull-out or a bathroom vanity drawer packed to the back. The Quadro V6 runs in frameless cabinets, fastening directly to the flat interior side panel, so it drops into production frameless boxes without adapters or face-frame brackets. For shops running a consistent frameless program, the 520mm Quadro V6 covers the depth most base drawers call for.
The Quadro V6 runner is steel throughout, finished in zinc for long indoor service life. Because the slide sits concealed beneath the drawer box, the zinc finish is a functional choice rather than a decorative one — it protects the mechanism while staying completely out of sight when the drawer is open. Ball bearings in formed steel raceways carry the load smoothly through the full travel, and the integrated soft-close damper is part of the slide body, not an add-on, so there are no extra parts to source or fail. Drawer side thickness compatibility runs from 1/2 inch to 5/8 inch (12.7 to 16mm); the 3/4 inch version of the Quadro line is a separate model and does not interchange with this one.
Production cabinet shops running frameless lines find the 520mm Quadro V6 a practical fit for standard base-cabinet depths. Custom shops use it where a concealed runner with soft-close is called for in client specifications and the drawer box is built from 5/8 inch dovetailed or doweled sides. Designers specifying handle-less or minimalist interiors rely on the Quadro line's clean look — nothing but wood visible from outside the cabinet. The 66 lb per pair rating covers the working loads of most residential kitchen and bath drawers without stepping up to a heavier-duty system.
Yes. This is the right-hand Quadro V6 member only. You need one right-hand and one left-hand slide to make a complete, working pair for a single drawer. Order the matching left-hand 520mm Quadro V6 separately.
Front locking devices for Quadro V6 are series-specific accessories. Confirm whether they are included with this SKU or need to be ordered separately before building your hardware list — locking devices from other undermount brands or Hettich series do not interchange with the Quadro V6.
This SKU is specified for frameless cabinets. Face-frame installs require rear mounting support behind the frame; check Hettich's lineup for a face-frame-compatible Quadro V6 configuration and the corresponding rear brackets before ordering for that construction.
Undermount slides require the drawer box to be built to the manufacturer's nominal length specification — in this case 520mm. Build the box to Hettich's published spec for the Quadro V6, including the correct box width for the side clearance, bottom recess, rear notch, and locking-device drilling. An off-spec box will not seat correctly on the runners.
Match the 520mm length to your drawer depth, confirm your box is built to the Quadro V6 specification for 1/2 to 5/8 inch sides, and order one right-hand and one left-hand member per drawer to complete the pair.
