Hettich KA4620 20" Side Mount Over-Travel 200 lb Ball Bearing Drawer Slide, Zinc, 9019958

Heavy-Load Drawer Slide That Reaches Past the Countertop

The Hettich KA 4620 is a 20 inch (500mm) side-mount ball bearing drawer slide rated at 200 lb, with over-travel action that carries the drawer 1-1/2 inches beyond full extension. That extra reach makes it the right call any time the cabinet sits beneath an overhang or a deep face frame.

Key Features

• 200 lb weight capacity — built for storage and utility drawers that would strain a standard 100 lb cabinet slide.
• 1-1/2 inch over-travel — the drawer member travels past the slide's nominal length so the back of the drawer clears a countertop overhang.
• Steel ball bearings in full-length raceways — smooth, consistent telescopic movement even under heavy loads.
• Non-handed design — the same slide fits the left and right side, so there's no sorting at the bench.
• Zinc finish on cold-formed steel — standard indoor corrosion protection for a side-mount slide that lives beside the drawer box.
• Standard motion — no soft-close, self-close, or detent mechanism; the drawer stays wherever it is left.

Where the Over-Travel Earns Its Place

Most full-extension slides stop at the cabinet face. On a counter with a 1-1/2 inch overhang, that puts the back of the drawer directly under the lip — technically open, practically awkward. The KA 4620's over-travel pushes the drawer past that point so the full interior is visible and reachable without leaning in. The same geometry applies under thick edge profiles, in retrofit installs where a face frame adds unexpected depth, and in any shop or utility run where a worktop overhangs the carcass. At 200 lb capacity, it also handles the loads those environments tend to produce: tools, hardware bins, and loaded shop drawers that would stress a standard kitchen-class slide.

Materials and Finish

The slide is cold-formed steel with a zinc finish. Zinc is the working standard for side-mount ball bearing slides: it resists indoor corrosion and holds up through years of daily cycling without adding bulk to the profile. This is a functional finish on a slide that sits beside the open drawer, not a decorative one. The steel construction handles the 200 lb rating without flex across the 20 inch span.

Who This Slide Is For

Cabinet shops and contractors running drawers under overhanging worktops will find the over-travel spec solves a real geometry problem without requiring a custom solution. Designers specifying heavy utility drawers — in a mudroom, a workshop, or a commercial millwork application — gain a load rating well above the residential kitchen class while staying in the familiar side-mount ball bearing format. Homeowners tackling a renovation with a deep countertop overhang will find installation straightforward: same 1/2 inch side clearance per side as a standard ball bearing slide, no handed sorting, standard 32mm mounting pattern. Note that no Hettich catalog is currently attached to confirm the side clearance specification for this series — verify the exact clearance requirement before building the drawer box to size.

The Right Slide for the Hard-to-Reach Drawer

When the drawer has to clear an overhang and carry a real load, the KA 4620's combination of over-travel reach and 200 lb capacity covers both problems in one standard-format side-mount slide.
