Zinc Ball Bearing Drawer Slide Built for Drawers That Push Past the Opening

This is a 28 inch side-mount ball bearing drawer slide from Knape and Vogt's 8455 series, rated 90 lb per pair, with integrated soft-close damping and 1 inch of over-travel that carries the drawer past the cabinet face. The zinc finish is the practical, low-profile choice for kitchen, office, and shop drawers where the hardware works hard and stays out of sight.

Key Features

• 1 inch of over-travel extends the drawer beyond the cabinet face, clearing countertop overhangs so the full drawer interior is reachable.
• Integrated soft-close catches the drawer near the end of travel and settles it shut quietly, even under load.
• 90 lb weight rating per pair handles a well-loaded kitchen or utility drawer.
• Steel ball bearings in full-length raceways deliver smooth, consistent travel across the full 28 inch length.
• Non-handed design means both slides in the pair are identical, with no left/right sorting on the bench.
• Zinc finish provides indoor corrosion resistance on a functional side-mount slide that sits beside the drawer box.

Where the Over-Travel Earns Its Place

A standard full-extension slide brings the drawer to the cabinet face — useful, but not always enough. When the drawer sits beneath a countertop overhang or behind a deep face frame, the last few inches of drawer contents stay out of reach. This 8455 series slide adds 1 inch beyond full extension, so the drawer clears the obstruction and the back of the box is actually accessible. That extra inch matters most in kitchen base cabinets with thick stone tops, in workbenches with overhanging surfaces, and in any run where the cabinetry's front projection competes with the drawer's opening travel. Pair that with the soft-close damper and the drawer closes quietly every time, regardless of how firmly it is pushed.

Zinc Finish on Working Hardware

Zinc plating over steel is the standard finish for side-mount ball bearing slides that spend their service life inside a cabinet box. It resists the mild humidity of indoor environments and holds up through years of daily cycling. Zinc is not a decorative finish — it will not be visible beside a closed drawer front — which is exactly why it is the right call for utility cabinetry, shop storage, and production runs where finish cost should follow function. This is an indoor slide; for wet or washdown environments, specify a stainless alternative.

Shops Running Volume and Installers Stocking Ahead

The 8455 series comes in a Bulk-Pack, which means the slides ship loose in a carton rather than individually bagged — the format that suits cabinet shops building multiple kitchens, contractors installing rows of base cabinets, and supply points that keep quantity on hand. The non-handed design keeps the bin simple: one SKU covers both sides of every drawer. Side clearance is 1/2 inch per side, so the drawer box is built 1 inch narrower than the cabinet opening. In face-frame cabinets, add matching rear mounting brackets — the brackets are series-specific and sold separately.

One Slide That Handles the Overhang Problem

When the drawer needs to clear the countertop and close quietly, the 8455 series in zinc delivers both without complicating the order or the install.
