A Zinc-Finished Heavy-Duty Slide Built for the Deepest, Most Demanding Drawers

The Knape and Vogt 8900 Series is a 60 inch full-extension side-mount ball bearing drawer slide rated 500 lb per pair, designed for industrial, commercial, and high-load storage applications where a standard cabinet slide would be nowhere near enough.

Key Features

• 500 lb weight capacity per pair — engineered for drawers that carry real industrial loads, well beyond the standard 100 lb kitchen-class range.
• 60 inch full extension — the drawer member travels the full slide length, bringing every inch of a deep drawer clear of the cabinet opening.
• Steel ball bearing construction — full-length raceways deliver smooth, controlled travel under maximum load.
• Zinc finish — electroplated zinc over steel provides reliable corrosion resistance for indoor service environments.
• Non-handed design — identical slides fit left and right, so there is no sorting on the bench and no risk of ordering a mismatched pair.
• 3/4 inch side clearance per side — wider than the standard half-inch clearance class; size the drawer box accordingly.

Where a 500 lb, 60 Inch Slide Belongs

A 60 inch full-extension slide in the 500 lb class is built for applications that would destroy a standard cabinet slide in short order. Think heavy-duty shop drawers carrying tooling and fixturing, industrial workbench pull-outs loaded with equipment, server or equipment rack drawers, and commercial storage units where the drawer needs to open completely and stay smooth under serious weight. The full-extension design means the back of even a 60 inch deep drawer comes all the way out to the cabinet face — rear contents are reachable without digging. Standard motion means no closing mechanism: the drawer stays wherever it is left, which is exactly right for work surfaces where a spring or detent would interfere with loading and unloading.

Steel and Zinc for Indoor Heavy-Duty Work

The 8900 Series runs on steel ball bearings in formed steel raceways — the construction that handles sustained heavy loads without the deflection or wear that lighter materials accumulate over time. The zinc finish is electroplated over the steel members and provides the corrosion protection expected of indoor industrial hardware. Zinc is a functional, durable finish suited to shop floors, equipment rooms, and storage facilities. This is not a stainless or sealed finish for wet or washdown environments; keep it in dry indoor applications and it will hold up through years of heavy cycling.

The Right Buyer for the 8900 Series at 60 Inches

Cabinet shops building custom workstations, millwork contractors specifying commercial storage, and facilities teams outfitting industrial storage racks are the natural buyers for this slide. The 500 lb rating and 60 inch length put it in a class that most residential and light commercial hardware never reaches. It arrives as a Bulk-Pack — the right format for shops and contractors ordering in volume rather than one-off retail quantities. The 3/4 inch side clearance per side is wider than the half-inch clearance on standard ball bearing slides, so draw boxes must be sized to leave 1-1/2 inches total across both sides. In face-frame cabinets, rear mounting support is required; confirm the matching rear bracket for this series before finalizing the installation plan.

Heavy Work, Done Right the First Time

When the drawer is deep, the load is serious, and the finish needs to hold up to an indoor industrial environment, the 8900 Series in zinc delivers the extension, the capacity, and the proven ball bearing travel to keep the installation performing over the long run.
