The Knape & Vogt 8455 series is a 90 lb class side-mount ball-bearing drawer slide with integrated soft-close damping and 1 inch of over-travel, sold as a bulk pack in a zinc finish. It is built for shop drawers, garage cabinetry, and commercial utility work where a loaded drawer needs controlled closing and full rear access past a countertop overhang or deep face frame.
Standard full-extension slides bring the drawer to the cabinet face — but in a shop with a bench overhang, or a kitchen with a deep face frame, the drawer back still hides behind the structure. The 1 inch of over-travel on this slide pushes past that obstruction so the back corner of the drawer is genuinely reachable, not just theoretically open. Pair that with soft-close damping and the drawer that gets pushed shut with a full hand does not bang against the cabinet box. That combination is the reason this slide fits utility drawers that see real daily use: parts drawers, tool drawers, and commercial casework drawers where the load is substantial and the closing behavior needs to be controlled.
The cabinet and drawer members are formed steel with a zinc finish — the workhorse protective coating for indoor drawer slides. Zinc plating holds up through the humidity cycles of a shop environment or an unheated garage cabinet, without the cost premium of stainless. The finish blends naturally with zinc-finished mounting hardware and standard interior panel colors. For installations where finish visibility matters at open, the zinc tone reads as a clean, functional metallic that does not compete with the cabinet interior. This slide is for indoor use; the zinc finish is not rated for exterior, marine, or washdown applications.
Cabinet shops building utility or shop-furniture runs reach for the bulk pack because there is no retail packaging to strip and no per-pair premium. Contractors fitting out commercial millwork with heavy drawers under worktops get the over-travel clearance without stepping up to a higher load class than the application needs. Garage and workshop builders who want soft-close on a 90 lb drawer — without paying for a 150 lb class slide they do not need — land here. The 1/2 inch side clearance requirement is the standard for side-mount ball-bearing slides, so existing drawer box sizing carries over from other side-mount projects without recalculation.
Per pair — the standard basis for drawer slide load ratings. Both slides together support 90 lb of drawer and contents.
No. The bulk-pack format ships slides without fasteners. Order screws appropriate to the slide's mounting holes and your cabinet material alongside this SKU.
The drawer member extends 1 inch past the slide's nominal 20 inch length. That extra inch carries the drawer box past a countertop overhang or deep face frame, so the rear of the drawer clears the opening completely. It is extra travel, not extra load capacity.
Yes, with the appropriate rear mounting support. Face-frame cabinets set the cabinet side back from the frame, so a rear mounting bracket or socket is needed to support the back of the slide. Those brackets are sold separately and must be compatible with this series.
The soft-close damper is integrated into the slide assembly, not a field-replaceable add-on. If damping performance changes over time, the slide itself would need to be replaced.
The 8455 series puts soft-close damping and over-travel access into one zinc-finished, bulk-packed slide that fits standard 1/2 inch side-mount clearances. Put the right load class on your drawers — and get controlled, quiet closing on every one of them.
