The Knape & Vogt 8650 Series is a 28 inch full-extension side-mount ball bearing drawer slide rated 150 lb per pair, with integrated soft-close damping and a zinc finish built for years of indoor service. It is the choice when a standard 100 lb cabinet slide is not enough and a quietly closing drawer matters.
A standard 100 lb cabinet slide carries most kitchen drawers without complaint. Step up to the 8650 when the load is genuinely heavier: deep drawer boxes packed with tools, pantry pulls loaded with canned goods, wide utility drawers in a shop or garage, or any application where the drawer routinely tests the limits of the standard class. At 28 inches, this slide suits deeper cabinet runs — think base cabinets in a full kitchen build or workbench drawers where the box runs nearly the depth of the cabinet. Full extension means the back of the drawer comes all the way to the cabinet opening; nothing stays hidden at the rear.
Steel members carry a zinc finish — the working standard across this segment and the right call for dry indoor installations. Zinc plating is not a decorative finish, and it is not stainless; it is a practical corrosion barrier that performs reliably in kitchen, shop, and utility environments. The slide sits beside the drawer box when open, so it is visible in use, and zinc blends cleanly with most cabinet interiors without drawing attention.
Cabinet shops building production runs of heavy-duty base cabinets, contractors fitting out workshops and utility rooms, and serious remodelers upgrading drawers that carry real loads will find the 8650 Series in the right class. The 1/2 inch side clearance per side matches the standard that most side-mount installations already plan for, so there is no special case dimensioning. The Bulk-Pack format suits shops that build in volume rather than one drawer at a time. For face-frame cabinet installations, rear mounting brackets are required to support the back of the slide — those brackets are sold separately and are series-specific.
Per pair. Each pair of slides — one on each side of the drawer — carries 150 lb combined. Do not double the number by counting each slide individually.
Damped. An internal damper slows the drawer through the last portion of closing travel and settles it shut quietly. This is not a spring-assisted self-close.
No. 28 inches is the closed length of the slide. Because this is a full-extension model, the drawer travels approximately its full length — but slide length and travel are two separate specs. Size the slide to your cabinet's interior depth, not the travel you want.
No. The 8650 Series is non-handed — one part fits either side, so every unit in the Bulk-Pack is identical and interchangeable.
Side-mount slides in face-frame cabinets need rear mounting brackets to support the back of the slide. Those brackets are sold separately and must match the 8650 series — do not use brackets from another KV series.
The 8650 Series in 28 inches brings the full-extension, 150 lb, soft-close combination to shops and installers who build more than one drawer at a time — reliable specs, zinc finish ready for indoor work, and Bulk-Pack pricing that keeps the build moving.
