Hettich Ball Bearing Drawer Slide For Worktop and Overhang Clearance

This is a 16 inch side-mount ball bearing drawer slide from Hettich's KA 4932 series, rated 150 lb and built with over-travel action that carries the drawer 1-1/2 inches past full extension — engineered for installations where countertop overhangs or deep face frames would otherwise block rear access to the drawer.

Key Features

• 150 lb weight capacity per pair — handles heavy storage drawers well above the standard 100 lb cabinet class.
• 1-1/2 inch over-travel — the drawer member extends past the slide's nominal length, pushing the box clear of countertop overhangs and deep face frames.
• Full-length ball bearing raceways — steel bearings deliver smooth, stable travel even under a heavy load.
• Non-handed design — identical slides fit both sides of the drawer, so there is no left/right sorting at the bench.
• Zinc finish on steel members — standard indoor corrosion protection suited to shop, kitchen, and office environments.
• Standard motion — no detent, damper, or spring; the drawer stays wherever it is left, making this slide compatible with push-to-open retrofits.

Where Over-Travel Makes the Difference

A standard full-extension slide stops at the cabinet face. When a countertop overhangs the drawer or a deep face frame sets the opening back from the box, the last few inches of the drawer stay in shadow and out of reach. The KA 4932's 1-1/2 inch over-travel solves that by pushing the drawer member past its nominal length, pulling the whole box free of the obstruction. Shop drawers under a workbench top, kitchen drawers under a thick slab edge, and utility drawers mounted behind a projecting frame are natural fits. The 150 lb rating means the added reach does not come at the expense of capacity — heavy tool trays and loaded storage drawers fall comfortably within spec.

Steel Construction and Zinc Finish

The KA 4932 is formed from steel and finished in zinc, the workhorse combination for side-mount ball bearing slides in indoor environments. Zinc plating protects the steel members through daily cycling in kitchens, offices, and shops. This is a functional, behind-the-door finish; it is not stainless and is not intended for wet or outdoor exposure. The 1/2 inch side clearance per side is the segment standard, so the drawer box sizing formula is straightforward: build the box 1 inch narrower than the cabinet opening.

Who Reaches For This Slide

Cabinet shops building base cabinets under thick stone or quartz tops reach for over-travel slides as a matter of course — the slab edge closes off standard travel and makes the rear of the drawer unreachable without it. Contractors fitting utility cabinets in garages and workshops face the same geometry whenever a workbench top overhangs the face. The 150 lb rating also makes this slide the right call for drawers that carry genuine weight: tool collections, hardware bins, and archive drawers loaded with binders. For drawer installations without an overhang challenge and a 100 lb load, a standard full-extension slide will do the job at lower cost; this SKU earns its place when both the extra reach and the higher capacity matter.

The Right Reach for Heavy Drawers in Tight Spaces

When the geometry of an overhang or deep frame would strand the back of a loaded drawer, the KA 4932's 150 lb rating and 1-1/2 inch over-travel combine the capacity and the clearance to solve the problem in one slide.
