The Hettich Quadro YOU IW21 is a right-hand, full-extension undermount drawer slide rated 90 lb and built for 350mm drawer boxes. It runs on ball bearings with integrated soft-close and is made for frameless cabinet construction, where it mounts directly to the cabinet side panel and disappears beneath the drawer box.
Short drawers — spice pull-outs, utensil trays, pencil drawers, and compact bathroom vanity boxes — benefit from a slide that delivers full access without over-specifying. A 350mm run opens the full box out to the face of the cabinet, so even a shallow drawer gives up nothing in reach. The 90 lb rating is more than sufficient for the loads these drawers typically carry, and the soft-close finish means the close stays quiet in kitchens, bathrooms, and built-ins where a slam would stand out.
Because this is a right-hand member, it is the correct side for an installer running a single replacement or adding a drawer to an existing case. Both sides must be ordered to equip a new drawer; the left-hand variant completes the pair.
Quadro YOU uses steel ball bearings running in formed steel raceways — the mechanism that keeps the pull smooth under load rather than getting stiff or gritty as the drawer fills. The zinc finish protects the steel through years of indoor service and blends with the typical frameless panel interior. This series mounts directly to the cabinet sidewall, which is the standard approach in frameless construction, and accommodates drawer sides from 1/2 inch to 5/8 inch thick. The slide stays concealed below the box, so the drawer interior presents clean wood sides with no visible hardware on the face.
Cabinet shops running frameless production lines reach for Quadro YOU when the specification calls for concealed full-extension soft-close without moving to a heavier or higher-cost system. The 350mm length fits naturally into a standard short-drawer program alongside 18-inch and longer runs in the same series, keeping the slide family consistent across the job. Designers specifying residential kitchens or bath vanities get the clean, handle-less-compatible aesthetic that undermount slides provide. Contractors replacing a slide on an existing frameless case can match this right-hand unit and get the drawer running again without changing the box or the cabinet.
This is the right-hand member only — one slide for one side of the drawer. To equip a drawer you need one right-hand and one left-hand unit. Order the matching left-hand variant to complete the set.
The Quadro YOU IW21 accommodates drawer sides from 1/2 inch to 5/8 inch thick. If your drawer box runs 3/4-inch sides, this version is not the right fit — check the Quadro YOU variants for the 3/4-inch side-thickness model.
This unit is rated for frameless cabinet construction, where the slide mounts directly to the flat interior panel. Face-frame installations require a different mounting approach and specific accessories; confirm the face-frame variant is in the Quadro YOU line before specifying for that application.
350mm converts to approximately 13-3/4 inches. Undermount slides require the drawer box to be built to the slide's nominal length, so the box should be built to the 350mm specification rather than matched to an inch measurement. If your existing box is a different depth, select the slide length that corresponds to that box depth.
Yes. Soft-close is integrated into the Quadro YOU slide — no add-on adapter or separate damper is needed. The damper is built into the slide mechanism and activates automatically as the drawer approaches the closed position.
Pair this right-hand Quadro YOU with its left-hand counterpart, build the box to the 350mm spec, and the drawer mounts concealed, pulls full, and closes quietly — the outcome that makes undermount slides the standard choice in finish cabinetry.
