Zinc Ball Bearing Over-Travel Slide Built for Heavy Shop and Storage Drawers

The Knape and Vogt 8815 Series is a 28 inch side-mount ball bearing drawer slide rated 190 lb per pair, with 1 inch of over-travel that carries the drawer past the cabinet face. It is the right slide when a worktable overhang, deep face frame, or countertop edge would otherwise block access to the back of a fully loaded drawer.

Key Features

• 190 lb load rating per pair — handles heavy shop, garage, and storage drawers well above the standard 100 lb cabinet class.
• 1 inch over-travel — the drawer member extends one inch past the slide's 28 inch length, clearing overhangs and deep front frames.
• Full steel ball bearing construction — precision ball bearings in formed steel raceways deliver smooth, controlled travel under load.
• Non-handed design — both slides in the pair are identical, so there is no sorting left from right on the bench.
• Zinc finish — electroplated zinc over steel provides indoor corrosion resistance on a functional, mostly hidden surface.
• Bulk-Pack packaging — boxed in trade quantity for shops and contractors ordering across multiple jobs.

Where Over-Travel Makes the Difference

A standard full-extension slide brings the drawer out to the cabinet face — but when a worktop overhangs the front, a deep face frame sits proud of the box, or the drawer sits under a counter edge, that stopping point leaves the rear of the drawer out of reach. The 8815's 1 inch of additional travel clears those obstructions and brings the whole drawer into view. This slide is a natural fit for shop benches with thick aprons, garage storage columns, server and utility closets, and commercial cabinetry where depth and load both push past what a standard 100 lb kitchen slide can handle. At 28 inches, it suits the deeper base cabinets and storage units common in production and institutional settings.

Materials and Finish

Steel members carry the structural load; ball bearings in full-length raceways distribute that load evenly through the travel cycle. The zinc finish is electroplated directly to the steel — it is the standard indoor corrosion protection for side-mount slides, not a decorative or outdoor-rated coating. The 3/4 inch side clearance requirement is wider than the 1/2 inch standard found on most 100 lb cabinet slides, so build the drawer box accordingly before ordering. This is a standard-motion slide with no closing mechanism: no soft-close damper, no self-close spring, no detent. The drawer rides freely and stays wherever it is left.

Who This Slide Is For

The 8815 in zinc serves shops, contractors, and institutional buyers who need a high-capacity side-mount slide in trade-friendly packaging without a color-specific finish requirement. Zinc is the neutral, go-anywhere finish for slides that will be hidden inside cabinets or behind drawer boxes — the right choice when the interior finish of the cabinet is not a factor and structural performance is the priority. Volume builders and multi-job contractors who work through pairs steadily will find the Bulk-Pack format matches how they actually buy. For face-frame cabinet installs, add the appropriate series-matched rear mounting brackets, sold separately, to support the slide's back end.

The Right Slide for Jobs That Push Past the Standard Class

When the load is real, the drawer is deep, and the front edge would block access on a plain full-extension slide, the KV 8815 in zinc delivers the capacity, travel, and packaging format that keeps the job moving.
