The Hettich Quadro YOU IW21 is a left-hand, full-extension undermount drawer slide rated at 90 lb, built for frameless cabinet installations where the drawer needs to close quietly and open completely. At 350mm nominal length, it suits standard kitchen and bath drawer depths and carries its load on a steel ball-bearing system with an integrated soft-close mechanism.
Full-extension undermount slides are the right call when the drawer's contents need to be fully accessible — pots-and-pans drawers, deep utensil drawers, and bathroom vanity pulls where reaching the back matters. The Quadro YOU IW21 suits those applications at a 350mm nominal length, which corresponds to standard North American drawer depths in production kitchen and bath cabinetry. The soft-close action eliminates the close-of-day cabinet slam in high-traffic residential installs and keeps the drawer quiet in commercial millwork settings where finish quality is scrutinized.
The slide is built from steel with a zinc finish — the standard corrosion-resistant coating for drawer slide members in indoor cabinetry. Ball bearings run between the members for smooth, consistent travel under load, and the integrated soft-close damper is part of the slide assembly rather than a bolt-on accessory. The zinc finish is functional and meant to be hidden: in a frameless cabinet the slide sits under the drawer box and stays out of sight when the drawer is open.
This slide is made for frameless (European-style) cabinets and mounts directly to the interior panel. The drawer box must be built to the Hettich Quadro YOU specification for 350mm nominal length, including the correct box width, rear notch, and locking-device drilling. Drawer side thickness must fall between 1/2 and 5/8 inch — the IW21 designation covers this range. Because this SKU is a single left-hand cabinet member, cabinet shops running full drawer sets need to order the matching right-hand member alongside it; ordering two of the same hand produces an unusable pair. Locking devices, front fixings, and rear brackets for the Quadro YOU are series-specific and are not interchangeable with other undermount brands or Hettich series.
This listing is for the left-hand cabinet member only. To complete one drawer, add the matching right-hand Quadro YOU IW21 member and the required locking devices.
This slide is designed for frameless cabinet construction. Face-frame installations require different mounting provisions; check that your cabinet type matches before ordering.
The IW21 version accepts drawer sides from 1/2 inch to 5/8 inch thick. If your box uses 3/4 inch sides, you need a different Quadro YOU variant.
Locking devices are not confirmed as included with this listing. Quadro YOU locking devices are series-specific — verify what is needed to complete the installation and order accordingly.
This is a full-extension slide, meaning the drawer member travels the full nominal length and brings the entire drawer box out to the cabinet face — the whole interior is reachable at full open.
When the drawer spec calls for a concealed, soft-closing full-extension undermount and the cabinet is frameless, this Hettich Quadro YOU IW21 left-hand slide covers that requirement at 350mm — provided the matching right-hand member and series-correct locking hardware complete the set.
