Zinc Ball Bearing Drawer Slide for Drawers Under Counter Overhangs

The Knape & Vogt 8405 series is a 16 inch side-mount ball bearing drawer slide with 1 inch of over-travel, rated 100 lb per pair, and finished in zinc. Where a standard full-extension slide stops at the cabinet face, the 8405 carries the drawer one inch further so the full drawer interior is reachable even when a countertop overhang sits in the way.

Key Features

• 1 inch over-travel pushes the drawer past full extension and clear of countertop overhangs or deep face-frame lips.
• 100 lb load rating per pair covers loaded kitchen, office, and utility drawers in the standard duty class.
• Hold-in anti-rebound detent keeps the drawer firmly closed and prevents it from bouncing back open after a firm push.
• Ball bearing telescopic construction delivers smooth, consistent travel from the first pull to the last.
• Non-handed design means both slides in the pair are identical — no left and right to sort on the bench.
• Zinc finish provides standard indoor corrosion resistance on cold-formed steel members.

Where Over-Travel Does Its Job

A standard full-extension slide brings a drawer to the cabinet face and stops there. That is enough for a cabinet with a flush or minimal overhang. In kitchens with a countertop that projects past the door line, or in casework with a thick face frame, the last inch of the drawer box can stay masked even when the slide is fully open. The 8405's 1 inch over-travel moves the drawer body past that obstruction, putting the rear of the drawer within reach without requiring you to lean around the counter edge. The same geometry helps on shop benches and workstations where a top surface overhangs the cabinet by an inch or so. The hold-in anti-rebound detent complements the over-travel function: after closing, the drawer stays put rather than rebounding back open when the bench or counter vibrates.

Materials and Finish

The 8405 is cold-formed steel with a zinc plating — the working standard for side-mount ball bearing slides in indoor cabinetry. Zinc protects the steel members through years of indoor cycling without adding visual weight; the slide sits beside the open drawer box where it is functional, not decorative. This is not a stainless or epoxy finish, and zinc-plated steel is suited to dry indoor environments. The bulk-pack format ships loose in a carton, the standard for shop and production orders.

Who Reaches for the 8405

Cabinet installers and kitchen shops use the 8405 when a job calls for over-travel at the standard 100 lb class — typically kitchens with stone or thick-edge countertops that project past the cabinet door, furniture pieces with applied top rails, or work surfaces where the top overhangs the box. The 16 inch length matches drawer boxes built for shallower wall cabinets, base cabinets with a short run, and utility cabinetry where a 20 or 22 inch slide would be too long. Because the design is non-handed, one bulk-pack quantity covers the full drawer count without splitting a left and right order. Build the drawer box 1 inch narrower than the cabinet opening to leave the required 1/2 inch of side clearance for each slide, and add the appropriate series rear mounting brackets for any face-frame cabinet installation.

The Right Reach for Tight Overhangs

When the countertop or top rail puts the back inch of a drawer out of reach, the KV 8405 is the straightforward fix: a zinc side-mount slide in the standard 100 lb class that travels 1 inch past full extension and stays closed reliably once shut.
