Zinc-Finished Heavy-Duty Ball Bearing Slides for File and Storage Drawers
The Knape and Vogt 8500 Series 26 inch full-extension side-mount ball bearing drawer slide is built for file drawers and heavy storage applications that push past the limits of standard cabinet-class hardware. Rated 150 lb per pair, it brings a stay-closed hold-in anti-rebound detent and progressive ball bearing movement to any drawer that needs to handle a real load.
Key Features
150 lb load class per pair — handles file drawers and loaded storage applications that would exceed a standard 100 lb cabinet slide.
Full extension — the entire drawer clears the cabinet opening, putting the back of even a deep 26 inch drawer within reach.
Hold-in anti-rebound detent — a mechanical catch keeps the drawer closed and prevents bounce-back after a firm push shut.
Progressive ball bearing movement — even under a full paper load, travel stays smooth and consistent across the full length of the slide.
Non-handed design — both slides in the pair are identical, so there is no left/right sorting on the bench.
Bulk-Pack quantity — packaged loose in carton quantities, suited to shops and contractors ordering for multiple installations at once.
Where a 26 Inch, 150 lb Slide Earns Its Keep
A lateral file drawer stocked with folders, a deep storage drawer in a workroom cabinet, a utility pull-out in a commercial millwork installation — these are the applications where a standard 100 lb cabinet slide runs short on capacity. The 8500 Series steps into that gap with a 150 lb class rating and a profile built for wider drawers, up to 36 inches across. At 26 inches of slide length, this is also the right choice when the cabinet interior runs deep and a shorter slide would leave the back of the drawer hard to reach. Full extension means the whole drawer box travels clear of the face frame, so nothing stays buried.
Steel Construction with a Zinc Finish
The slide members are formed from steel and finished in zinc — the same corrosion-resistant coating that has been the indoor standard for side-mount ball bearing slides across decades of commercial and cabinet work. Zinc protects the steel through years of daily cycling without adding bulk. It is a functional finish, not a decorative one; the slide sits beside the open drawer and stays mostly out of sight in use. For installations where the slide is visible against a darker cabinet interior, the same 8500 Series is available in other finishes.
The Right Fit for File Drawers and Commercial Casework
Cabinet shops building office furniture, millwork contractors installing lateral file banks, and facilities managers sourcing replacements for worn-out file hardware all land on the same need: a slide that handles real weight without adding mechanisms that file drawers do not require. There is no soft-close to interfere with heavy use, no spring assist to fight when loading a drawer to capacity — just a hold-in detent that keeps the drawer shut until pulled, and 26 inches of smooth, full-extension travel. The 1/2 inch side clearance per side matches the standard side-mount ball bearing format, so the drawer box formula is straightforward. Sold as a Bulk-Pack, this SKU is sized for volume: shops running multiple drawer banks or contractors staging hardware for a full installation can order at quantity without repackaging.
Is the hold-in detent the same as soft-close?
No. The hold-in anti-rebound detent is a mechanical catch that holds the drawer closed and stops it from bouncing back after it is pushed shut. There is no damper and no spring assist — the drawer does not pull itself closed, and it does not slow near the end of travel. For a damped soft-close, look at the Fulterer FR 5001 or KV FM soft-close series.
How wide a drawer can this slide support?
Knape and Vogt recommends a maximum drawer width of 36 inches for the 8500 Series full-extension model at this load class.
Do I need to order a left-hand and a right-hand slide?
No. The 8500 Series is non-handed — both slides in the pair are the same part, and either one mounts on either side of the drawer.
What side clearance does this slide require?
The slide needs 1/2 inch of clearance between the drawer box side and the cabinet interior on each side. Build the drawer box 1 inch narrower than the cabinet opening to hit that number on both sides.
Will this slide work in a face-frame cabinet?
Side-mount slides in face-frame cabinets need rear support because the cabinet side is set back from the face frame. Add the matching KV rear mounting brackets, sold separately, to support the back end of the slide.
What does Bulk-Pack mean for this SKU?
Bulk-Pack means the slides ship loose in a carton rather than in individual retail bags. It is the standard packaging for shop and contractor orders; confirm the per-unit quantity at checkout.
Built for the Drawer That Gets Used Hard
When the load is real, the drawer is deep, and the installation needs to hold up over years of daily use, the KV 8500 Series 26 inch slide in zinc delivers the capacity and the stay-closed reliability to keep work moving.
