Zinc Finish and File-Drawer Strength in a Single 22 Inch Slide
The Knape and Vogt 8500 Series 22 inch full-extension ball bearing drawer slide is a 150 lb class side-mount slide built for file drawers, lateral cabinets, and heavy storage drawers that outpace what a standard 100 lb cabinet slide can handle. It ships in a Bulk-Pack, making it the practical choice for shops and contractors outfitting multiple drawers at once.
Key Features
150 lb load class per pair — rated well above the standard kitchen-cabinet range, sized for drawers loaded with files, tools, or hardware.
Full extension — the drawer clears the cabinet face completely, putting the rear contents within reach.
Hold-in anti-rebound detent — a mechanical catch keeps the drawer firmly closed and stops it from bouncing back open after a firm push.
Progressive ball bearing movement — steel ball bearings in full-length raceways deliver smooth, even travel under a full load.
Non-handed design — one slide fits either side of the drawer, so there is no sorting left from right on the bench.
Bulk-Pack format — loose in a carton for high-volume installs, without retail packaging overhead.
Where the 150 lb Rating Earns Its Place
A drawer full of hanging files, heavy-gauge fasteners, or shop tools can push past the 100 lb ceiling of a standard cabinet slide without the buyer noticing until the slide labors or the bearing race deforms. The KV 8500 series is built for that load class — KV recommends it for drawers up to 36 inches wide, which covers most lateral file and wide utility applications. The hold-in anti-rebound detent is especially useful here: a heavy drawer pushed shut with some force would ordinarily bounce back open; the detent catches it and holds it in place until intentionally pulled. There is no spring assist and no damper, just a positive mechanical catch that does its job without adding complexity.
Steel Construction with a Zinc Finish
The slide members are cold-formed steel with a zinc finish — the same functional, corrosion-resistant surface that has made zinc the standard for side-mount ball bearing slides in indoor cabinetry. Zinc is not a decorative coating; it protects the steel through years of cycling in a shop, office, or storage environment without calling attention to itself beside the open drawer. This is an indoor application finish; it is not rated for wet, exterior, or washdown environments.
The Right Fit for High-Volume and Heavy-Duty Work
Cabinet shops running lateral file cabinets, office furniture builders, and contractors specifying heavy-duty storage casework all reach for the 8500 series when the load exceeds the standard class. The Bulk-Pack format suits that volume: loose in a carton, priced for quantity, without individual retail bags adding cost. The 1/2 inch side clearance per side matches the standard side-mount footprint, so the 8500 drops into the same layout as a 100 lb slide without rebuilding the drawer box — just confirm the box is built to handle 150 lb of contents. The non-handed design means every slide in the carton is interchangeable, which simplifies both ordering and assembly-line installation.
Common Questions
Is 22 inches how far this slide opens?
No. Twenty-two inches is the closed length of the slide. Because this is a full-extension model, the drawer member travels approximately the full slide length, bringing the entire drawer out to the cabinet face — but slide length and travel distance are separate specs.
Is the hold-in detent the same as soft-close?
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed and stops it from rebounding after a firm push. There is no damper and no spring pull — the drawer stays put until you pull it open. Soft-close requires a separate damped mechanism, which this slide does not include.
Do I need a left and a right version?
No. The 8500 series is non-handed — both slides in a pair are identical. Every slide in the Bulk-Pack carton fits either side of any drawer.
Can I install this in a face-frame cabinet?
Yes, but face-frame construction requires rear support at the back of the slide. Add the matching KV rear mounting brackets for the 8500 series, sold separately. The brackets are series-specific and are not interchangeable with brackets from other slide lines.
How is the drawer removed for cleaning or service?
The 8500 series uses KV's quick-disconnect drawer members. Extend the drawer fully and lift the front of the drawer member off the cabinet rail — no tools required.
Bulk Quantity, Built for the Work That Shows Up Every Day
When the job calls for a slide that handles real file-drawer loads, stays closed without bouncing, and installs the same way on every side of every drawer, the KV 8500 series in the Bulk-Pack format keeps the work moving from the first drawer to the last.
