The Knape and Vogt 6500 series is a 22 inch full-extension side-mount ball bearing file drawer slide, rated 125 lb per pair and built for the deeper drawers that routinely exceed the capacity of standard 100 lb cabinet slides. It is the right starting point when the drawer carries files, tooling, or dense storage rather than light kitchen contents.
File drawers loaded with hanging folders, lateral files stacked with binders, or shop drawers holding tooling can push a standard 100 lb slide close to its limit before the drawer is even full. The 6500 series steps that ceiling up to 125 lb per pair, giving the installation a reasonable margin under everyday use. Full extension means the drawer member travels the full length of the slide, so nothing stays hidden at the back of the cabinet when the drawer is open. This is a standard-motion slide: no self-close ramp, no soft-close damper, no detent. The drawer rides on the bearings and stays wherever it is left.
The slide members are cold-rolled steel, zinc plated for indoor corrosion resistance. Zinc is the standard functional finish for this class of slide: it protects the steel through years of regular use without adding cost or visual weight. These slides sit beside the drawer box and are visible when the drawer is open, so the clean zinc appearance keeps the cabinet interior looking orderly. This finish is for dry, indoor installations — not for wet or exterior environments.
Cabinet shops building file pedestals, office furniture, or tool storage cabinets will find the 6500 series in the right load class for the job. It also fits contractors and woodworkers who need reliable full-extension travel at a capacity that clears the standard 100 lb threshold without stepping into purpose-built heavy-duty hardware. The 22 inch length suits standard legal-depth and lateral file drawers, as well as deeper utility and shop cabinets. Both frameless and face-frame installations are possible; face-frame cabinets need rear mounting brackets at the back of the slide, sold separately. Each slide requires 1/2 inch of side clearance, so the drawer box is built 1 inch narrower than the cabinet opening. Sold as a bulk-pack pair.
No. 22 inches is the closed length of the slide. Because this is a full-extension slide, the drawer member travels approximately the full slide length, bringing the entire drawer out to the cabinet face — but slide length and travel are two separate facts.
No. The 6500 series is a standard-motion slide with no closing mechanism. The drawer stays wherever it is left. If soft-close is needed in a side-mount application, look at a dedicated soft-close slide in the same length and clearance.
No. The design is non-handed — both slides in the pair are identical, and either one fits either side of the drawer.
In a face-frame cabinet the back of the slide needs rear support. Add the matching rear mounting brackets for the 6500 series, sold separately. No extra hardware is needed for frameless cabinet installations.
The 6500 series uses a lever disconnect. Actuate the levers on both slides simultaneously and pull the drawer straight out.
When the job calls for full extension at a load class that handles real file or storage weight, the KV 6500 series in 22 inches delivers without overbuilding the spec or the budget.
