This is a 28 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 6500 series, rated 125 lb per pair and built specifically for file and lateral drawers that demand both depth and load capacity.
Deep drawers create a specific problem: contents at the back are invisible and hard to reach when the slide doesn't pull far enough. At 28 inches, this slide is sized for lateral file cabinets, deep shop storage drawers, and institutional casework where standard 18 or 22 inch cabinet slides leave the rear of the drawer inaccessible. Full extension means the drawer member travels approximately the full slide length, clearing the cabinet face completely — the back of the drawer is as reachable as the front. The 125 lb per pair rating covers a fully loaded file drawer without asking the slide to work outside its class.
The 6500 series is cold-formed steel throughout, with a zinc finish for indoor corrosion resistance. Zinc is the working standard for side-mount ball bearing file slides: functional, durable, and unobtrusive beside the drawer box in everyday use. This is not a decorative finish and is not rated for outdoor or high-moisture environments — it's engineered for the long cycles of an office or commercial cabinet in a dry interior space.
The 6500 series targets a specific buyer: anyone building or replacing hardware in lateral file cabinets, deep storage drawers, or commercial casework who needs more capacity than a standard 100 lb kitchen slide provides. At 125 lb per pair and 28 inches, it sits between the economy cabinet class and the heavier-duty 150 lb file slide programs. For a shop pulling through multiple installs, the Bulk-Pack format removes retail packaging from the equation. In face-frame cabinets, rear mounting brackets are required to support the back of the slide — add the matching series brackets, sold separately. The slide requires 1/2 inch of side clearance per side, so build the drawer box 1 inch narrower than the cabinet opening.
Those are two separate measurements. 28 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 the slide length and the travel distance are not the same number to design around.
The 125 lb rating is per pair — that's the capacity for one complete drawer installation using both slides. Do not double it by counting each slide separately.
No. The 6500 series is a standard-motion slide — no damper, no spring, and no detent. The drawer stays wherever it is left. If a closing feature matters, look at soft-close or self-close variants in a compatible length.
No. The design is non-handed, so every slide in the pack is identical. Both fit either side of the drawer.
In a face-frame cabinet, the back of the slide needs rear mounting brackets for support. The brackets are sold separately and must match the 6500 series — rear mounting hardware is not universal across slide brands or series.
When the drawer is 28 inches deep and loaded with files, the slide doing that job needs to match the task — in length, load class, and travel. The KV 6500 series at this length is the direct answer for that application, without over-specifying into a heavier class or under-serving with a shorter, lighter slide.
