The Knape and Vogt 8500 Series 20 inch full-extension side-mount ball bearing slide is built for the duty class that overloads standard cabinet hardware. Rated at 150 lb per pair and sized for file and lateral drawers, this slide brings everything in the drawer out to the cabinet face and keeps it there — the hold-in anti-rebound detent stops the drawer from bouncing back open after a firm close.
A standard 100 lb cabinet slide is the right tool for a pots-and-pans drawer or an office supply cabinet. A loaded lateral file is a different problem: folders, hanging rails, and dividers add up quickly, and a drawer that bounces back open mid-load interrupts work. The 8500 series is sized for that application — 150 lb per pair covers a lateral file drawer heavy with paper, and full extension means the rear hanging files come all the way out to the face of the cabinet instead of staying buried at the back. The hold-in detent keeps the closed drawer where you left it until you pull it again.
The 8500 slide is formed from steel with a zinc finish that protects the members through years of repeated indoor use. Zinc is a functional, not decorative, finish — it handles the friction and corrosion resistance demands of a production environment without adding unnecessary cost. The slide profile is taller than a standard cabinet slide to accommodate the quick-disconnect drawer member rail, which lets the drawer lift free without tools when the member is extended.
The 8500 series belongs in any drawer where the load class, not the aesthetics, drives the specification. That includes office file pedestals, lateral filing cabinets, shop storage drawers carrying tooling or hardware, and any other pull-out where the contents routinely push past what a standard kitchen-cabinet slide is rated for. KV rates the 8500 for drawers up to 36 inches wide. Build the drawer box 1 inch narrower than the cabinet opening to leave the required 1/2 inch side clearance per slide. In face-frame cabinets, rear mounting support is required — add the matching KV rear mounting brackets, sold separately, as the series-specific fit is not interchangeable with other KV bracket styles.
No. The 8500 series is a heavier-built slide in the 150 lb class, designed specifically for file and lateral drawers. Standard cabinet slides in this catalog are typically rated at 100 lb per pair; the 8500 is built with a taller profile and a quick-disconnect drawer member rail to handle the higher load and wider drawer widths that file applications demand.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer in the closed position and stops it from bouncing back open when shut firmly. It does not pull the drawer shut, and there is no damper. The drawer closes manually; the detent holds it there until pulled.
The 8500 series uses KV's quick-disconnect drawer member rail. With the drawer extended, the drawer member lifts free of the cabinet member without tools — no squeeze levers needed.
The Bulk-Pack is a trade carton quantity. Check the pack quantity shown in the product spec block for the exact count per carton; each slide in the carton is non-handed and fits either side of the drawer.
Yes. Face-frame cabinets set the cabinet side back from the front frame, so the rear of the slide needs support from a rear mounting bracket. The brackets are series-specific to the 8500 and are sold separately; they are not the same part used on the KV 8400 series.
When the drawer is a lateral file or a heavy storage pull-out and a standard 100 lb slide is not the honest answer, the KV 8500 Series 20 inch slide gives you the capacity, the full-extension travel, and the stay-closed detent the application actually calls for.
