Zinc-Finished Over-Travel Ball Bearing Drawer Slide For Drawers Under Worktop Overhangs

The Knape and Vogt 8405 Series is a 20 inch over-travel side-mount ball bearing drawer slide that carries the drawer one inch past full extension, rated 100 lb per pair, and finished in zinc for lasting indoor service. It is the right choice when a countertop overhang or deep face frame would otherwise block access to the rear of the drawer.

Key Features

• One inch of over-travel carries the drawer past the cabinet face, clearing countertop overhangs and deep face frames.
• 100 lb weight capacity per pair handles loaded kitchen, office, and utility drawers in the standard duty class.
• Hold-in anti-rebound detent keeps the drawer closed after a firm push and prevents it from bouncing back open.
• Zinc finish over steel provides dependable corrosion resistance for years of indoor use.
• Non-handed design means both slides in the pair are identical, so there is no left-right sorting on the bench.
• Poly-Pack packaging delivers the pair bagged and ready, with mounting hardware included.

Where Over-Travel Makes the Difference

A standard full-extension slide brings the drawer out to the cabinet face — enough for most kitchen and office work. The 8405 goes one inch further. That extra travel matters most under a countertop with a significant overhang, behind a deep face frame, or in any situation where the last few inches of the drawer are the ones that get used most. The hold-in anti-rebound detent adds a practical benefit at the other end of travel: when the drawer is pushed shut, the detent catches and holds it in place rather than letting it bounce back. This is not a spring-close or a soft-close — the drawer stays wherever it is put and closes firmly without springing back.

Steel and Zinc Built for the Long Run

The slide members are cold-formed steel with a zinc electroplate finish — the proven standard for side-mount ball bearing slides in cabinetry and shop work. Zinc protects the steel from the moisture and humidity found in kitchen and utility environments without adding bulk or weight to the profile. The finish is functional rather than decorative, which is appropriate for a slide that sits beside the drawer box and is mostly out of sight when the drawer is closed. Ball bearings run in full-length raceways between the members for smooth, consistent travel under load throughout the life of the installation.

The Right Drawer for This Slide

This slide suits cabinet shops and contractors fitting drawers beneath worktops with overhangs, as well as homeowners replacing slides in an existing kitchen where the counter profile cuts off access to the drawer at full open. At the 100 lb per pair rating, it covers the full range of standard kitchen, bath, and home office drawers without stepping into the heavier file-drawer class. Build the drawer box one inch narrower than the cabinet opening to leave 1/2 inch of side clearance for each slide. In a face-frame cabinet, rear mounting brackets are required to support the back of the slide; those brackets are series-specific and sold separately.

One Inch Further, Every Time the Drawer Opens

For drawers that have always come up just short of full access, the 8405 over-travel series closes the gap — and the zinc finish and hold-in detent make sure the installation holds up over years of daily use.
