Zinc Ball Bearing Slide For Drawers That Clear the Overhang

The Knape and Vogt 8455 series is a 22 inch side-mount ball bearing drawer slide that pairs over-travel action with an integrated soft-close damper, finished in zinc for lasting indoor service. It is the right choice when a countertop overhang, deep face frame, or appliance garage puts the back of the drawer just out of reach at full extension.

Key Features

• Over-travel extension carries the drawer 1 inch past full extension, so it clears overhangs and deep frames that trap a standard slide at the cabinet face.
• Integrated soft-close damper catches the drawer near the end of travel and settles it shut silently — no slam, no rattle.
• 90 lb weight capacity per pair handles a fully loaded kitchen, utility, or office drawer.
• Non-handed design means the same slide fits either side of the drawer, with no left/right sorting at the bench.
• Zinc finish provides standard indoor corrosion resistance on cold-formed steel members.
• Bulk-Pack packaging ships loose in a carton, suited to cabinet shops ordering in volume rather than retail packs.

Where Over-Travel and Soft-Close Work Together

A standard full-extension slide opens to the cabinet face and stops. Under a countertop overhang or behind a 1-1/4 inch face frame, that stop leaves the back inch of the drawer hidden. The 8455 series pushes the drawer member 1 inch past nominal extension, pulling the rear contents into view. The soft-close damper then handles closing: once the drawer is pushed within the capture zone, the mechanism takes over and brings it home without noise or impact. That combination — one extra inch on the open side, a controlled close on the shut side — suits kitchen drawers beneath a stone overhang, home-office drawers under a built-in desktop, and any cabinet where both access and quiet matter.

Steel Construction and Zinc Finish

The slide members are cold-formed steel with a zinc plated finish. Zinc is the working standard for side-mount ball bearing slides because it protects the steel through the humidity cycles of a kitchen or bath environment without adding visual weight to an already utilitarian component. The finish is functional, not decorative — the slide sits beside the open drawer box, mostly out of sight. Ball bearings run in full-length raceways between the members for smooth, consistent travel through both the extended over-travel range and the soft-close zone.

Specifying the 8455 Series

This slide is built for cabinet shops, designers, and contractors running volume kitchen and built-in projects where the finished look demands quiet operation and the cabinet geometry demands over-travel. At 90 lb per pair it covers standard residential drawer loads; it is not a heavy-duty or file-class slide. The 1/2 inch side clearance per slide is the segment standard — build the drawer box 1 inch narrower than the cabinet opening. In frameless cabinets the slide mounts directly to the interior side panel. In face-frame cabinets, add the matching series rear mounting brackets, sold separately, to support the back of the slide. The Bulk-Pack format delivers the slides loose in a carton, which is practical for high-volume installs where retail packaging is waste.

The Right Slide for Tight Geometries and Quiet Kitchens

When the cabinet layout takes away the last inch of drawer travel and noise is not an option, the 8455 series resolves both problems in one slide — over-travel recovers the reach, and soft-close handles the close.
