This is a 16 inch full-extension side-mount ball bearing file drawer slide from Knape and Vogt's 8500 series, rated in the 150 lb class per pair. Where a standard 100 lb cabinet slide runs short on capacity, the 8500 steps in — sized for file drawers, lateral pulls, and dense storage drawers that see real weight day after day.
A standard kitchen or utility drawer rarely pushes 100 lb, but a file drawer loaded with hanging folders, a lateral file full of binders, or a parts drawer packed with hardware can get there quickly. The 8500 series is built around that reality. Full extension means the drawer comes all the way out — the back of a 16 inch drawer reaches the cabinet face at full open, which matters when the rear files are the ones you need. The hold-in anti-rebound detent is equally practical in a busy office or shop: close the drawer firmly and it stays closed, rather than rebounding into the aisle.
The slide members are steel with a zinc finish, the standard corrosion-resistant coating for side-mount ball bearing slides in indoor service. The zinc finish is functional, not decorative — these slides sit beside the drawer box and are mostly out of sight in normal use. For file, office, or utility drawers that stay inside a conditioned building, the finish holds up through years of daily cycling.
Cabinet shops building office furniture and file credenzas reach for the 8500 when the drawer specification calls out 150 lb capacity. Contractors outfitting a law office, an archive room, or a parts-storage bay get the load class they need without stepping into a heavy-duty industrial product. The 16 inch length suits shallower file pedestals and storage cabinets where a longer slide would crowd the back of the cabinet. The Bulk-Pack format fits shops ordering slides by the box rather than by the pair — the per-unit cost drops and inventory stays ahead of the build schedule. In face-frame cabinets, add the matching KV rear mounting brackets, sold separately, to support the back end of the slide.
Per pair. One pair of 8500 series slides — one on each side of the drawer — carries the 150 lb class load together. Do not count each slide separately when sizing for a drawer.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed after you push it shut. It does not pull the drawer closed, and there is no damper. The drawer stays wherever you leave it; the detent prevents bounce-back on a firm close.
KV recommends a maximum drawer width of 36 inches for the 8500 series. That covers most file pedestals, lateral files, and storage cabinet drawers at this slide length.
The slide requires 1/2 inch of side clearance per side. Build the drawer box 1 inch narrower than the cabinet opening to leave the correct gap for each slide.
No. The 8500 series is non-handed — both slides in the pair are identical parts. Order the quantity your job requires without worrying about handedness.
When the drawer carries paper, binders, or parts weight that a standard cabinet slide is not rated for, the 8500 series in the 150 lb class is the straightforward answer — full extension, stay-closed detent, and volume packaging for the shop that builds more than one at a time.
