This is a 16 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8908 series, rated 500 lb per pair and finished in zinc. It combines a hold-in detent that keeps the drawer closed and a hold-out detent that holds it fully open — the double-detent combination built for industrial, shop, and commercial drawers where contents shift and the drawer needs to stay exactly where you put it.
Shop tool drawers, industrial storage carts, service-counter drawers, and institutional cabinets all share a common problem: contents that shift during use or vibration can bounce a drawer open or pull it shut at the wrong moment. The hold-in detent keeps the closed drawer in place until someone pulls it with intent. The hold-out detent locks the open position so both hands stay free while work is happening. Neither requires a keyed lock — each releases with a normal push or pull. At 500 lb per pair, the load class is well beyond what a loaded kitchen or file drawer asks for; this is the slide to reach for when the contents are heavy tools, parts bins, or anything that puts real weight on the rails.
The slide members are cold-formed steel finished in zinc, the working standard for side-mount ball bearing slides that live inside a cabinet or cart and do their job out of sight. Zinc plating handles indoor moisture and the routine abrasion of drawer cycling without the weight or cost of a specialty corrosion-resistant alloy. This is not an outdoor or washdown finish; for those environments, verify the appropriate corrosion-resistant material before specifying. The zinc on the 8908 series is a functional choice that keeps the steel protected through years of heavy-cycle service.
Cabinet shops fitting out a dedicated tool storage unit, contractors building service carts, and facility managers sourcing heavy institutional drawers are the core buyers for this series. The 500 lb rating and double-detent action put it well outside the residential kitchen range — this is commercial and industrial hardware that happens to fit a standard side-mount installation. Because the slide is non-handed, one part number covers both sides of the drawer, which simplifies ordering for shops running volume. The bulk-pack format suits that same audience: no retail packaging, just the slides ready to go.
The 500 lb rating is per pair. Each individual slide carries half that load as part of the working system — do not treat the per-pair number as each slide's individual capacity.
No. The hold-out detent is a mechanical catch that releases with a normal push. There is no lever, key, or tool required — push the drawer and it closes.
The 8908 series is a heavier-built slide with a larger cross-section than standard cabinet slides. Build the drawer box 1-1/2 inches narrower than the cabinet opening — 3/4 inch per side — rather than the 1 inch reduction used for standard slides.
A side-mount slide in a face-frame cabinet needs rear support. Add matching rear mounting brackets at the back of the cabinet to carry the slide's rear end. The 8908 brackets are series-specific; do not substitute brackets from other KV lines.
No. The hold-in detent keeps the drawer from drifting open once closed, but there is no spring pull and no damper. This is a standard-motion slide with mechanical detents — the drawer stays where you leave it.
When the drawer has to hold 500 lb, stay closed on its own, and stay open while work happens, the 8908 series in zinc is the straightforward answer — full extension, double detent, heavy steel, ready for the bench.
