This is an 18 inch full-extension side-mount ball bearing file drawer slide from Knape & Vogt's 8500 series, rated 150 lb per pair with a hold-in anti-rebound detent that keeps loaded drawers from bouncing back open after a firm close.
A standard 100 lb cabinet slide is right for pots and pans, but a lateral file drawer loaded with hanging folders regularly pushes past that threshold. The 8500 series is built for exactly that load class: the 150 lb per-pair rating covers deep file drawers, heavy shop drawers, and utility pull-outs storing tools or dense materials. The hold-in anti-rebound detent adds a practical benefit in these applications — a heavy drawer pushed shut with some force stays shut instead of bouncing back into the opening. KV recommends this series for drawers up to 36 inches wide, making it the right fit for lateral file cabinets as well as standard single-wide file drawers.
The slide members are cold-formed steel with a zinc finish, the standard corrosion-resistant coating for indoor side-mount ball bearing hardware. Zinc protects the steel through years of daily cycling in an office, shop, or cabinet environment. This is a functional, mostly hidden finish — the slide sits beside the drawer box and is not a decorative element. The 8500 series runs taller than standard cabinet slides, which accounts for its higher load capacity and the quick-disconnect drawer member design at the back end.
Cabinet shops building file pedestals, office furniture manufacturers running lateral file drawers, and facility maintenance teams replacing worn-out file hardware are the natural buyers for this slide. The non-handed design and Bulk-Pack format suit shops that run multiple units at once — no left/right inventory to manage, and no retail packaging waste. The 32mm hole pattern aligns with production frameless cabinet panels directly. For face-frame file cabinets, add the matching KV rear mounting brackets, sold separately; the brackets are series-specific and not interchangeable with other KV lines.
Per pair. Each drawer uses two slides, and the 150 lb figure is the combined working capacity for that pair.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed once it is pushed shut and prevents it from bouncing back open. It does not pull or spring the drawer shut on its own — push the drawer to fully closed and the detent engages.
KV recommends the 8500 series for drawers up to 36 inches wide, which covers most standard and lateral file drawer widths.
The slide requires 1/2 inch of side clearance per side. Build the drawer box 1 inch narrower than the cabinet opening to accommodate both slides.
No. The 8500 series is non-handed — both slides in the pair are identical and fit either side of the drawer.
Yes, but the slide's back end needs support. In face-frame construction, add the KV rear mounting brackets (sold separately) that are matched to the 8500 series. Brackets from other KV series are not interchangeable.
The KV 8500 series 18 inch slide does its job without requiring adjustment after installation: mount it, load the drawer, and the 150 lb rating and anti-rebound detent handle the rest across years of daily use.
