This is a 22 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8908 series, rated 500 lb per pair in a zinc finish, with hold-in and hold-out detents for drawers that need to stay exactly where they are placed.
At 500 lb per pair, the 8908 series is not a kitchen cabinet slide — it is built for shop benches, industrial carts, server and equipment racks, and any commercial installation where a standard 100 lb or 150 lb slide would be undersized. The combined hold-in and hold-out action makes it equally useful in mobile or vibration-prone settings: the hold-in detent prevents a loaded drawer from bouncing open, while the hold-out detent keeps the drawer extended hands-free while work is being done inside it. Full extension means the back of the drawer is reachable, not buried — a practical requirement when the drawer carries tools, parts, or heavy stock.
The 8908 series is formed from steel and finished in zinc, which is the workhorse corrosion-resistant coating for heavy-duty indoor slide applications. Zinc holds up in shop environments where humidity and handling are higher than in a residential cabinet, and it does so without the cost premium of stainless. The finish is functional rather than decorative — it sits beside the drawer box in a utility context, and its job is durability over years of heavy cycling, not appearance. This SKU ships in bulk-pack format, making it a practical choice for shops or contractors installing multiple drawers from the same order.
The 8908B 22 requires 3/4 inch of side clearance per side — more than the 1/2 inch clearance standard cabinet slides call for. Build the drawer box 1-1/2 inches narrower than the cabinet opening to accommodate both slides. Because the slide is non-handed, every unit in the order is interchangeable, which simplifies both staging and installation. In face-frame cabinets or enclosures, rear mounting support is needed at the back of the slide; use the series-matched brackets for this application, sold separately. The 8908 series is the right specification when load capacity and the hold-in/hold-out combination are both required — not as a substitute for a lighter slide, and not interchangeable with standard-clearance hardware in an existing box already built to 1/2 inch.
Hold-in is a detent that keeps the drawer closed and prevents it from bouncing or drifting open. Hold-out is a separate detent that keeps the drawer in the fully open position until deliberately pushed closed. Both release with normal force — neither is a positive lock. On this slide, both detents are active, so the drawer stays put in either position.
500 lb is the rating per pair — that is, for both slides working together on one drawer. Do not double this number by counting each slide separately.
The 8908 series is a heavy-duty slide with a larger physical profile than standard cabinet ball bearing slides. The wider side clearance accommodates that profile. If you are replacing a slide that used 1/2 inch clearance, the existing drawer box width will need to be adjusted before this slide can be used.
No. The hold-in detent keeps the drawer closed once shut, but there is no damper. The drawer does not slow down automatically before closing — it stays wherever it is placed or pushed.
Bulk-pack means the slides ship loose in a carton rather than individually packaged. It is a trade-quantity format suited to shops and contractors installing several drawers at once from a single order.
When the application calls for 500 lb capacity and a drawer that stays exactly where it is left — open or closed — the KV 8908 series in zinc delivers both without compromise.
