Hettich KA 4620 Over Extension Drawer Slide (400 mm)

Overview

The Hettich KA 4620 is a telescopic over-extension drawer runner built for full drawer access in kitchen cabinets, wardrobes, and storage furniture. It is engineered with a pull-out stop and roll-out guard, offers a 90 kg loading capacity, and is made from galvanised, blue-passivated steel with a zinc finish. The runner set is manufactured in Taiwan and backed by a 10-year warranty.

What It Does

The KA 4620 allows a drawer to extend fully beyond the cabinet face (over-extension), giving users complete visibility and access to items stored at the back of the drawer. The integrated roll-out guard prevents the drawer from being pulled out accidentally, and the pull-out stop provides controlled, stable motion during use.

Who It Helps

• Kitchen and furniture manufacturers sourcing drawer channels for cabinet production
• Interior designers and modular kitchen fabricators specifying hardware for client projects
• Contractors and carpenters installing or replacing drawer slides in cabinetry
• Homeowners upgrading existing drawers that need full-extension access and higher load capacity

Comparison Context

Within Hettich's Drawer Channels range, the KA 4620 sits under Telescopic Channel – Regular, specifically the KA 4620 series. It is positioned as a standard-duty over-extension slide (90 kg capacity, normal closing) rather than a soft-close or heavy-duty model, making it suited for general kitchen and cabinet drawers rather than high-load or premium soft-close applications.
