This is a 26 inch side-mount ball bearing file drawer slide from Knape and Vogt's 8500 series, rated 150 lb per pair with 1 inch of over-travel beyond full extension and a hold-in anti-rebound detent that keeps the loaded drawer from bouncing back open.
The extra inch of travel past full extension matters most in two common situations: lateral file drawers installed below a countertop overhang, and drawers in cabinets with deep face frames. In both cases a plain full-extension slide stops short, leaving the rearmost hanging folders out of reach. The 26 inch length suits deeper-than-average lateral and legal-size file cabinets where a shorter slide would either not fit the cabinet or leave the drawer box undercut. At 150 lb per pair, the 8505 series handles a drawer fully loaded with paper-weight contents — a task that regularly exceeds what standard 100 lb cabinet slides are rated to carry.
The slide is formed from steel with a zinc finish, the standard for indoor corrosion protection on side-mount ball bearing hardware. Zinc is a functional finish rather than a decorative one — it protects the steel members through years of office or shop service. The progressive ball bearing system distributes load across the travel rather than concentrating it at the front of the stroke, which is why this series is specified for file drawers rather than lighter kitchen cabinetry. The 3.79 inch profile height accommodates the quick-disconnect rail that lets the drawer member be removed without tools.
This slide is the right fit for office furniture builders, commercial cabinet shops, and facilities teams replacing worn slides in existing lateral or legal file cabinets. The 26 inch length and 150 lb class step past what standard kitchen drawer hardware can handle, and the over-travel feature is worth specifying any time the finished cabinet will sit beneath a worktop or feature a pronounced face frame. The bulk pack format suits shops running this size in volume; the non-handed design keeps inventory simple. In face-frame cabinet installations, add the matching KV rear mounting brackets — they are series-specific and sold separately. Build the drawer box 1 inch narrower than the cabinet opening to provide the required 1/2 inch side clearance for each slide.
No. Twenty-six inches is the closed slide length. Because this is an over-travel slide, the drawer member travels the full slide length plus an additional 1 inch beyond it — so total travel exceeds 26 inches.
The hold-in anti-rebound detent is a mechanical catch that stops the drawer from bouncing back open after a firm close. It does not pull the drawer shut and it does not damp the close — there is no spring assist and no damper on this slide.
The bulk-pack format is a trade quantity carton. Confirm the per-carton count on the product page or with your account representative before ordering to ensure you are getting the quantity your project requires.
No. The 8505 series is non-handed — both slides in a pair are identical and either one fits either side of the drawer.
Yes, but face-frame installations require rear mounting brackets to support the back end of the slide. Those brackets are series-specific and sold separately — order KV rear brackets matched to the 8500 series.
When the lateral cabinet sits below a worktop and the drawer needs to clear it fully, the 26 inch 8505 delivers the load capacity, over-travel, and stay-closed reliability that standard file hardware cannot match.
