520mm Actro 5D Full Extension Undermount Drawer Slide RH 88lb Capacity Steel Hettich 9257082

Right-Hand Undermount Runner for Deep Frameless Cabinet Drawers

The Hettich Actro 5D is a right-hand ball-bearing undermount drawer slide rated 88 lb, built for 520mm (nominally 21 inch) drawers in frameless cabinets. It delivers full-extension travel with integrated soft-close and five-axis front adjustment, staying completely hidden beneath the drawer box when the drawer is open.

Key Features

• Full-extension travel brings the entire 520mm drawer out to the cabinet face so every inch of the interior is reachable.
• Integrated soft-close catches the drawer near the end of travel and settles it shut quietly without a separate add-on damper.
• 88 lb load rating handles a fully loaded kitchen, utility, or file drawer with capacity to spare.
• Actro 5D five-axis adjustment lets the installed drawer front be trued in height, side, depth, tilt, and skew after hanging.
• Ball-bearing mechanism runs smoothly under load across the full travel range.
• Right-hand orientation — pair with the matching left-hand runner to complete one drawer installation.

Where Full Extension and Soft-Close Work Together

A 520mm drawer is long enough that the contents at the rear are genuinely hard to reach at 3/4 extension. Full extension solves that: the drawer clears the cabinet face completely, so pots at the back of a base cabinet, files at the rear of a deep office drawer, or supplies in a utility pullout are in reach without leaning in. The integrated soft-close means that same heavy, fully loaded drawer settles shut quietly every time — no slamming from a drawer returned with any force. For production kitchens and residential cabinet shops running frameless boxes, that combination at this length handles the deeper base and tall cabinet drawers that come up most often in a build.

Construction and Fit

The Actro 5D runner is steel with a zinc finish — a functional, corrosion-resistant surface suited to the cabinet interior environment. The slide is engineered for frameless (European-style) cabinet construction, mounting directly to the flat side panel. It accepts drawer sides from 1/2 inch to 5/8 inch thick, which covers the most common plywood and solid-wood drawer box stock thicknesses used with undermount systems. Because undermount slides require the drawer box to be built to the slide's nominal length and notched to spec at the rear, the drawer box must be constructed to the Hettich Actro specification — including the correct rear notch and locking-device drilling — before installation. The five-axis adjustment built into the Actro 5D locking device means minor front-alignment corrections happen at the slide, not by shimming or rehanging the box.

Who Reaches for This Runner

Cabinet shops running frameless production lines are the natural fit: the Actro 5D installs on the 32mm grid, adjusts fast once the box is hung, and the integrated soft-close eliminates a separate adapter step. Designers specifying premium residential cabinetry reach for it when handle-less fronts or quiet operation is part of the brief and the drawer depth calls for a 520mm slide. Contractors doing finish installs appreciate the five-axis correction range — real-world frameless boxes are not always perfectly square, and the adjustment built into this runner absorbs the variation without a callback. This is a right-hand runner sold as a single unit; one right-hand and one left-hand runner make a complete drawer pair.

A Concealed Runner That Earns Its Keep in Deep Drawers

The Actro 5D at 520mm pairs full extension with integrated soft-close and broad drawer-side compatibility in a concealed runner built for frameless production — a practical choice for the deeper draws in any kitchen or cabinet build.
