The Knape and Vogt 8908 series is a 32 inch, 500 lb rated full-extension side-mount ball bearing drawer slide built for the most demanding shop, industrial, and commercial drawer applications. Zinc finished steel and a non-handed design make it straightforward to spec and install wherever a heavy drawer needs to stay put when closed and stay open when working.
At 500 lb per pair, this slide is in a different duty class than a kitchen cabinet slide. It belongs under heavy steel toolbox drawers, loaded shop storage, commercial service counters, and institutional casework where a standard 100 lb or 150 lb slide would be undersized. The hold-in detent stops a loaded drawer from bouncing back open after a firm push, which matters when drawer contents are heavy enough to shift momentum. The hold-out detent keeps the drawer fully open while both hands are occupied at the bench — no reaching back to push it out again mid-task. Full extension means the back corner of a 32 inch deep drawer comes out to the cabinet face, not hidden behind a face frame.
The 8908 series is cold-formed steel with a zinc finish — the same durable, corrosion-resistant coating standard across heavy-duty side-mount slides for indoor service. Zinc is a working finish, not a decorative one. It handles the humidity and wear of a shop or commercial environment without the cost premium of stainless. For outdoor, washdown, or marine applications, stainless is the right call; for dry indoor work at this duty class, zinc holds up through years of daily cycling. The ball bearings run in full-length steel raceways, which is what keeps travel smooth and controlled under the kind of loads this slide is rated for.
Cabinet shops building out custom workbenches, millwork firms installing commercial service counters, and contractors fitting institutional storage all land on this series when the load spec pushes past what a standard heavy-duty slide handles. The 32 inch length suits deep tool storage and commercial drawer applications where a shorter slide would leave drawer depth on the table. The non-handed design is especially useful in production runs — no sorting left from right on the bench, no mismatched pairs at the end of the job. This SKU ships in a bulk pack, which suits shops ordering in quantity for a multi-drawer project rather than a single replacement.
The 8908 series is rated at 500 lb per pair, putting it in the extra-heavy-duty class — five times the capacity of a standard kitchen slide. The body profile and bearing system are built for that load, not scaled up from a lighter design.
Hold-in is a detent that keeps the drawer closed and prevents it from rebounding open after a firm push. Hold-out is a separate detent that holds the drawer in the fully open position until intentionally pushed closed. Neither function is a lock — both release with a normal pull or push. There is no damper; this is not a soft-close slide.
Yes. Most standard side-mount ball bearing slides use 1/2 inch of clearance per side. This series requires 3/4 inch per side, so build the drawer box 1-1/2 inches narrower than the cabinet opening rather than the usual 1 inch. Measure carefully before cutting stock.
No. The 8908 series is non-handed — both slides in the pair are identical and fit either side of the drawer without modification.
Side-mount slides at this duty class need rear support in face-frame construction. Add the appropriate series rear mounting brackets for face-frame installs; the cabinet side is set back from the face frame and the slide's back end needs something to bear against. Brackets are sold separately and are series-specific.
When the drawer is heavy enough that a standard slide is not even close, the 8908 series delivers 500 lb capacity, stay-closed and stay-open detents, and full extension in a zinc-finished side-mount package that goes in without handing.
