This is the right-hand cabinet member from Knape and Vogt's 8500 series, a 20 inch side-mount ball bearing slide component rated in the 150 lb class per pair and designed specifically for file and lateral drawers that would push a standard cabinet slide past its limits. It ships in a Q-Pack quantity format for shops installing multiple file drawer stations at once.
A loaded lateral file drawer can hit 100 lb on its own, and a standard kitchen-class slide is not the right tool for that job. The KV 8500 series is built around the file drawer use case: a 150 lb class rating per pair handles the weight, and the hold-in anti-rebound detent means the drawer stays closed when someone shoves it shut rather than drifting or bouncing back open. The full-extension design brings the entire drawer out to the cabinet face, so the rear hanging files are just as reachable as the front ones. At 20 inches, this cabinet member suits office and built-in file drawer applications where the cabinet depth accommodates that length.
The cabinet member is formed steel with a zinc finish — the working standard for side-mount ball bearing slides in indoor environments. Zinc provides reliable corrosion resistance through years of daily office use without adding unnecessary weight or cost. The 8500 series profile is taller than a standard cabinet slide to accommodate the quick-disconnect drawer members and the structural demands of the file drawer load class. The slide uses progressive ball bearing movement, which distributes load smoothly across the full travel rather than concentrating stress at any single point.
This SKU is the right-hand cabinet member only — not a complete slide pair. It is the right order for a shop building multiple file drawer stations that sources cabinet and drawer members separately, or for a service replacement of a damaged right-hand cabinet member on an existing 8500 series installation. The Q-Pack format makes it practical for production runs and multi-drawer office furniture builds. Specify this part when the cabinet construction is frameless, with the 1/2 inch side clearance per side built into the drawer box width. For face-frame cabinets, add the matching KV rear mounting brackets, sold separately, to support the back end of the slide.
This is the right-hand cabinet member only. A complete drawer requires the left-hand cabinet member and both drawer members (left and right). Order all four components in the matching 8500 series and 20 inch length.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed and prevents it from bouncing back open — there is no damper and no spring assist. The drawer does not slow down as it closes.
KV recommends a maximum drawer width of 36 inches for the full-extension 8500 series at the 150 lb class rating. This is wider than the 24 inch maximum recommended for the standard 8400 series, which suits the lateral file use case well.
Yes, but face-frame installations require rear mounting brackets to support the back end of the slide, since the cabinet side is set back from the frame. The matching KV rear brackets are sold separately and are specific to the 8500 series.
No. 20 inches is the closed length of the slide. Because this is a full-extension slide, travel is approximately the full slide length — the drawer clears the cabinet opening — but slide length and drawer travel are two separate specifications.
When the drawer carries real office loads, matching the slide class to the job keeps the installation working smoothly for years — and having the right-hand cabinet member available in a Q-Pack quantity means the build doesn't stall waiting on parts.
