This is a 12 inch side-mount ball bearing file drawer slide from Knape and Vogt's 8505 series, rated 150 lb per pair and built with 1 inch of over-travel so the drawer clears obstructions at the cabinet opening. It is the shortest member of the 8505 family, matched to shallow file drawers and tight cabinet installations where full-depth hardware will not fit but load capacity cannot be compromised.
Shallow drawers in compact workstations, pedestal file units, and lateral file cabinets with limited interior depth are the natural fit here. At 12 inches, this slide handles drawers that a standard 18 or 22 inch unit simply cannot reach. The 1 inch of over-travel is the difference between digging for contents at the back of the drawer and having the whole interior come out to meet you — especially useful when the cabinet sits under a countertop overhang or inside a built-in where the face frame adds depth at the opening. The 150 lb class rating covers a compact drawer loaded with dense files, tools, or supplies that would exceed what standard kitchen-class slides are rated to carry.
The 8505 series is built from steel members with a zinc finish — the working standard for indoor ball-bearing side-mount slides and the finish most likely to disappear against a painted or melamine cabinet interior. Zinc protects the steel through years of daily cycling in an office or shop environment. This is a functional hardware finish, not a decorative one; the slides sit beside the drawer box and are mostly out of sight when the drawer is closed.
The 8505 is the right call when two conditions line up: the drawer needs more than the standard 100 lb class can offer, and over-travel is a genuine requirement rather than a nice-to-have. Cabinet shops fitting pedestal desks, compact storage units, and shallow base cabinets under worktops will find the 12 inch length useful where longer slides create interference. Build the drawer box 1 inch narrower than the cabinet opening to give each slide the required 1/2 inch of side clearance. In face-frame cabinets, rear mounting brackets are required to support the back end of the slide; those brackets are series-specific and sold separately. This SKU ships in a bulk carton — confirm the pack quantity for your project before ordering.
No. Twelve inches is the closed length of the slide. The drawer travels its full nominal length plus the 1 inch of over-travel — so it extends past the cabinet face by that extra inch. Slide length and travel are two different measurements.
It is a mechanical catch that keeps the drawer in the closed position and prevents it from springing back open after being pushed shut firmly. It does not pull the drawer closed, and it does not damp the closing motion — it simply holds. There is no soft-close or self-close feature on this slide.
The 8500 is a full-extension file slide rated in the same 150 lb class. The 8505 adds 1 inch of over-travel so the drawer member extends past the slide's nominal length — useful when a countertop overhang or face frame would otherwise block access to the rear of the drawer. Both are non-handed and carry the same hold-in anti-rebound detent.
No. The 8505 is non-handed, so both slides in the pair are the same part. Order the total number of slides your drawer count requires.
Not without support at the rear. Face-frame cabinets set the cabinet side back from the opening, so the slide needs a rear mounting bracket to carry its back end. Knape and Vogt rear brackets for this series are sold separately; confirm the correct bracket model for the 8505 before ordering.
When the cabinet is shallow, the load is heavy, and the opening has an overhang, the 12 inch KV 8505 covers all three constraints in one slide — 150 lb capacity, over-travel clearance, and a stay-closed detent for a drawer that behaves itself at close.
