This is a 34 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8908 series, rated 500 lb per pair, with a zinc finish and combined hold-in/hold-out detents that keep the drawer locked in place whether open or closed. It is built for drawers that carry genuine industrial loads, not standard cabinet work.
Most side-mount ball bearing drawer slides are sized for kitchen and office drawers in the 75 to 150 lb class. The 8908 series exists for applications where that range is simply not enough: mechanics' tool storage, industrial workbenches, server equipment pulls, heavy-gauge steel parts drawers, and commercial service carts. At 34 inches, the slide carries a deep drawer under a full work surface, and full extension means the entire drawer clears the opening — no reaching past a partly-open front to get to the back. The hold-in detent prevents a loaded drawer from bouncing back open after a firm close, and the hold-out keeps the drawer at full extension when both hands are occupied with the work at hand.
The 8908 series is cold-formed steel with a zinc finish — the functional standard for heavy-duty ball bearing slides intended for indoor shop, industrial, and commercial environments. Zinc provides reliable corrosion resistance in dry interior conditions and is the finish that matches unpainted steel shop furniture and bare cabinet interiors. This is not a decorative finish, and it is not rated for washdown, marine, or outdoor exposure. For those environments, review the stainless or coated variants in the series.
Because this is a heavy-duty slide with a wider profile than standard cabinet slides, the required side clearance is 3/4 inch per side — not the 1/2 inch that applies to most side-mount ball bearing slides. Build the drawer box 1-1/2 inches narrower than the cabinet opening to achieve that clearance on both sides. In face-frame cabinet installations, rear mounting support is required; use the matching rear brackets for this series, sold separately. The non-handed design means the same slide goes on either side without sorting or flipping at the bench.
It means the slide has a mechanical detent in both the closed and fully-open positions. The detent holds the drawer firmly in each position and releases with normal pulling or pushing force. This is not a keyed or lever lock — it will not stop intentional movement, but it does prevent drift, rebound, and unwanted travel.
500 lb is the rating per pair — the two slides working together as an installed set. Do not double this number to estimate total capacity.
No. The 8908 series requires 3/4 inch of side clearance per side. A drawer box built to the narrower 1/2 inch clearance will not seat or travel correctly in this slide.
Full extension means the entire drawer clears the cabinet opening — the drawer member travels approximately the full slide length. The 34 inch figure is the closed slide length. Travel and slide length are close on a full-extension slide, but they are two separate specs.
No. The 8908 series is non-handed — both slides in a pair are identical and fit either side of the drawer.
When the drawer is loaded beyond what any standard cabinet slide can handle and the job demands a positive hold in both positions, the 8908 series in zinc is the straightforward answer — full extension, 500 lb capacity, and detents that keep work moving instead of chasing a drawer that drifts or rebounds.
