This is a 20 inch full-extension side-mount ball bearing drawer slide from Knape & Vogt's 8400 series, rated 100 lb per pair, with a hold-in anti-rebound detent and a zinc finish. It ships in a bulk pack, making it a practical choice for cabinet shops and contractors building drawers in volume.
The 20 inch length matches a drawer box built for a cabinet with roughly 21 to 22 inches of interior depth, leaving room for the slide and any rear hardware. Full extension means the back of the drawer clears the opening entirely, which matters on kitchen base cabinets, utility drawers, and shop storage where rear access is part of the everyday workflow. The hold-in detent makes this a natural fit for drawers that need to stay shut without a soft-close mechanism — shop benches, office credenzas, and entry-level residential work where the budget calls for a clean, functional slide without motion upgrades.
The slide members are cold-formed steel with a zinc finish. Zinc is the workhorse finish in this segment: it resists corrosion in dry indoor environments, blends into a painted or melamine cabinet interior, and holds up through the daily cycle counts a production cabinet sees over its lifetime. This is a functional finish, mostly hidden beside the open drawer box. It is not a decorative or stainless finish, and it is suited to interior cabinetry rather than wet or outdoor applications.
Cabinet shops running production lines reach for the bulk pack because it keeps the bench stocked without reordering after every few jobs. The non-handed, lever-disconnect design speeds installation: no sorting, no consulting a diagram, and drawers pull free cleanly for finishing or adjustment. Contractors specifying standard residential cabinets get a reliable 100 lb full-extension slide at a volume-friendly price. The 8400 series is KV's core medium-duty line — the right call for the wide middle of residential and light-commercial drawer work, not for loaded file drawers or drawers that need soft-close damping.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed and stops it from bouncing back open after a firm push. There is no damper and no spring — the drawer stays where it is left until intentionally pulled. Soft-close is a separate, damped feature not present on this slide.
This slide requires 1/2 inch of side clearance per side, so build the drawer box 1 inch narrower than the cabinet opening to fit the pair correctly.
It can, but face-frame construction sets the cabinet side back from the front frame, so the rear of the slide needs support. Add the matching KV rear mounting brackets, sold separately, for a proper face-frame install.
Mounting hardware inclusion varies by pack configuration. Check the pack contents listed on the product page or confirm with your sales contact before the job starts.
The 8400 series is rated 100 lb per pair in the standard cabinet duty class. A loaded file or lateral drawer often exceeds that — for file duty, step up to the KV 8500 series, which is built and rated for that application.
The KV 8400 series in the 20 inch zinc bulk pack gives production shops a full-extension, hold-in slide they can trust across a whole project run — consistent fit, straightforward install, and a detent that does its job quietly every time.
