The Knape and Vogt 8900 Series is a 28 inch, full-extension side-mount ball-bearing drawer slide rated at 500 lb per pair, finished in zinc for long-lasting indoor service. Built for drawers that carry real weight and open fully every time, this slide suits shop benches, utility cabinets, and commercial casework where load capacity is the first spec on the list.
A 500 lb rating changes what a drawer can do. Tool storage cabinets loaded with hand tools and hardware, workbench drawers carrying power tool accessories, parts bins in a production shop, and utility cabinets in a garage or warehouse are all applications where a standard kitchen-class slide runs out of capacity long before the drawer does. The 28 inch length suits deep cabinet boxes built for full-depth storage, and full extension means the contents at the very back of the drawer are reachable without reaching into the cabinet. Standard motion is the right call here: in a shop or industrial setting, a drawer that stays open while both hands are busy is an advantage, not a missing feature.
Zinc plating over steel is the workhorse finish for indoor ball-bearing slides — it resists the light moisture and handling of a shop environment without the cost premium of stainless steel. The zinc coat blends into natural wood and painted steel interiors without drawing attention, which suits utility cabinetry where function matters more than the look of the hardware. This slide is built for dry, indoor applications; for washdown or high-humidity environments, a stainless option is the right specification.
Cabinet shops building shop furniture, commercial millwork outfitters specifying heavy-duty utility runs, and contractors sourcing slides for storage rooms and warehouse casework will all find the 8900 series a straightforward fit. The 3/4 inch side clearance required per side is the standard for this class of side-mount ball-bearing slide, and the non-handed design means a single SKU covers both sides of every drawer. Homeowners tackling a serious garage cabinet build or a heavy-duty workbench will get the same industrial-grade result from these slides that a production shop would.
Yes. Full extension brings the drawer member out to the full slide length, so the back of the drawer box clears the cabinet opening and the entire interior is accessible.
The 500 lb rating is the capacity for the pair as listed — that is the load the installed set carries together, not a per-side figure.
Plan for 3/4 inch of clearance per side — build the drawer box 1-1/2 inches narrower than the cabinet opening to leave the right gap for both slides.
No. The 8900 series uses standard motion with no self-close ramp or soft-close damper. The drawer stays in whatever position you leave it, which is often preferable in a shop or utility setting.
Yes. The slide is non-handed, meaning the same part works on the left and right sides of every drawer without a separate left-hand or right-hand order.
When the application calls for 500 lb of capacity, full access to a deep 28 inch drawer box, and a finish that holds up over years of indoor use, the KV 8900 Series in zinc delivers without complication — straightforward specs, a non-handed design, and a load rating built for the jobs that standard cabinet slides cannot handle.
