Hettich KA4620 18" Side Mount Over-Travel 200 lb Ball Bearing Drawer Slide, Zinc, 9019957

Zinc Steel Ball Bearing Slide for Heavy Drawers Under a Worktop

The Hettich KA 4620 is an 18 inch (450mm) side-mount ball bearing drawer slide rated 200 lb, with over-travel that carries the drawer 1-1/2 inches past full extension. It is built for heavy storage drawers that need to clear a countertop overhang or a deep face frame to give real access to the back of the box.

Key Features

• 200 lb weight capacity — handles loads that exceed the standard 100 lb cabinet class, including loaded shop drawers and heavy tool storage.
• 1-1/2 inch over-travel — the drawer member extends 1-1/2 inches beyond the slide's nominal length, clearing counter overhangs so the full drawer interior is reachable.
• Full-length ball bearing raceways — steel ball bearings deliver smooth, consistent travel even when the drawer is carrying a heavy load.
• Non-handed design — the same slide fits either side of the drawer, so there is no left/right sorting on the bench.
• Standard motion — no detent, spring, or damper; the drawer stays wherever it is left and opens freely with a pull.
• Zinc-finished steel — corrosion-resistant for years of indoor service without a decorative finish requirement.

Where Over-Travel Makes the Difference

A standard full-extension slide brings the drawer out to the cabinet face. That is enough for most kitchen cabinets, but not for a drawer positioned under a countertop overhang, behind a deep face frame, or beneath a workbench surface. The KA 4620's 1-1/2 inches of over-travel push the box past the obstruction, so the rear contents are within reach without leaning in. This matters most in shop and utility cabinets where drawers are deep, loaded, and accessed from a standing position. At 200 lb capacity, the slide is also ready for drawers that a standard cabinet slide simply is not rated to handle.

Materials and Construction

The slide is formed from steel and finished in zinc, the working standard for side-mount ball bearing slides in indoor environments. Zinc plating provides everyday corrosion resistance against shop humidity and cleaning. The ball bearings run in continuous steel raceways that span the full slide length, keeping travel smooth and true under load across the slide's service life. This is a functional, work-oriented finish, not a decorative one — it is engineered to be reliable, not visible.

Who This Slide Is For

The KA 4620 in 18 inches suits woodworkers, contractors, and shop builders specifying drawers that combine real weight with constrained access. A cabinet shop fitting out a utility room under a granite countertop, a contractor building a workbench with a low overhead shelf, or a homeowner replacing undersized slides on a heavy tool chest will all find the 200 lb rating and the 1-1/2 inch over-travel doing useful work together. The non-handed format keeps inventory simple: one SKU serves both sides of every drawer in the run.

Common Questions

The Right Slide for Heavy Drawers in Tight Spaces

When the drawer is heavy and the opening is tight, the KA 4620's 200 lb rating and 1-1/2 inches of over-travel work together to solve both problems at once — getting the full drawer clear of the obstruction and keeping it supported under load.
