The Knape and Vogt 4450 series is a 20 inch full-extension side-mount ball bearing drawer slide with integrated soft-close, finished in zinc. Rated 65 lb per pair, it brings damped, quiet closing to standard cabinetry without adding bulk to the cabinet interior.
Soft-close is now a baseline expectation on residential kitchen and bath cabinetry, and the 4450 series delivers it in a side-mount format that installs the same way a plain ball bearing slide does. The 20 inch length suits standard base cabinet drawers, and the full-extension travel means the homeowner can reach the pot at the back of the pots-and-pans drawer or the file at the rear of a shallow office pedestal. The 65 lb per pair rating covers most loaded residential drawers — cookware, linens, files, and similar contents. For heavier-duty applications, step up to the 100 lb class slides in the catalog.
Zinc is the standard functional finish for steel side-mount slides, and it is the right call here. The 4450 sits beside the drawer box, mostly hidden when the drawer is closed and visible only when the drawer is open. The zinc electroplate protects the steel members through years of indoor service and daily cycling. This is not a decorative or stainless finish, and it is not rated for wet or exterior environments — the 4450 is an indoor cabinet slide.
Cabinet shops and designers specifying the 4450 should build the drawer box 1 inch narrower than the cabinet opening to leave 1/2 inch of side clearance for each slide. The low-profile body helps where interior width is tight. In frameless cabinets the slide mounts directly to the cabinet side panel. In face-frame cabinets, rear support is required — add the matching rear mounting brackets, sold separately, to carry the back end of the slide. The Bulk-Pack format is sized for shops ordering in volume, not individual retail packs.
True soft-close. The 4450 series uses an integrated damper that slows the drawer to a controlled, quiet close over the last portion of travel. It is not a spring ramp or a detent — the closing action is damped.
Full extension means the intermediate member lets the drawer travel out to the cabinet face, so the entire interior of the drawer is reachable. The 20 inch measurement is the closed length of the slide, not a travel distance — but on a full-extension slide the travel closely matches the nominal length.
No. The 4450 is non-handed, so both slides in the pair are the same part and fit either side of the drawer.
Face-frame installations require rear mounting brackets to support the back end of the slide, since the cabinet side is set back from the frame. The brackets are sold separately and are series-specific — confirm the correct bracket for the 4450 before ordering.
Pack quantity is shown in the ordering details on this page. Bulk-Pack format ships without individual retail packaging, which is the standard choice for production cabinet shops.
The Knape and Vogt 4450 in zinc gives a cabinet shop a consistent, spec-able soft-close side-mount slide that installs without surprises and delivers the quiet close residential customers expect on every drawer in the job.
