Hettich Quadro YOU IW21 left drawer slides with 90lb capacity give a single drawer bank a strong left-side runner, so the slide carries everyday loads without sagging, which helps drawers track straight in cabinet use. The 350mm length establishes how deep the drawer can be built on this runner, so cabinet and drawer box dimensions can be laid out confidently around that working depth. Full extension action moves the drawer fully out of the cabinet, so the user can access items at the back without shifting contents or working around a partially hidden box. The undermount layout positions the slide underneath the drawer, so the runner stays out of the way of the interior, which keeps the drawer sides visually clear for clean cabinet lines. The soft-closing function slows the last part of travel, so the drawer settles into the cabinet more gently during normal operation.
The undermount layout of this Hettich Quadro YOU IW21 left drawer slide places the runner below the drawer, so installers work with bottom clearances and rear setbacks instead of side-mount gaps. The 350mm length gives a fixed reference dimension from the cabinet front to the slide end, so cabinet case drilling and drawer box length can be coordinated around that specific size. The full extension travel ensures the slide moves the drawer completely out of the opening, so alignment of drawer fronts can be checked with the drawer open and closed through its entire stroke. The 90lb capacity indicates the performance range this slide is intended to handle, so builders can plan drawer width and typical contents around a known working load rating.
This Hettich Quadro YOU IW21 left drawer slide with 350mm length suits drawer boxes built around that depth inside cabinet cases, so projects that match this dimension can use the full stroke of the slide. The undermount design supports cabinet layouts where clean drawer sides and a clear interior are a priority, because the hardware runs below the box instead of along the side. The full extension travel brings the drawer fully forward in the opening, so users can reach items at the back without leaning into the cabinet, which suits base cabinets, vanities, and similar storage runs.
The 350mm length on this slide provides a consistent base dimension, so multiple drawer boxes in a run can be built to the same depth and still operate with full extension movement. The 90lb capacity gives a repeatable load reference across a project, so drawers built on this left runner can be planned for similar contents without changing hardware style. The undermount construction means the drawer rides on hidden hardware, so face and side clearances can be laid out the same way from drawer to drawer, which helps maintain uniform reveals across a cabinet bank. The soft-closing function provides controlled closing over the final part of travel, so drawers in repeated use feel consistent from one opening to the next.
