Zinc-Finished Over-Travel Ball Bearing Drawer Slides for Worktop and Overhang Installations

The Knape and Vogt 8405 Series is a 24 inch side-mount ball bearing drawer slide with 1 inch of over-travel beyond full extension, rated 100 lb per pair, finished in zinc, and sold as a poly-pack pair. It is the right slide when a standard full-extension model leaves the rear of the drawer just out of reach under a countertop overhang or deep face frame.

Key Features

• 1 inch over-travel carries the drawer past the cabinet face, clearing countertop overhangs so the back of the drawer is fully reachable.
• 100 lb weight rating per pair handles a fully loaded kitchen or utility drawer with room to spare.
• Hold-in anti-rebound detent keeps the drawer closed after a firm push, preventing bounce-back without spring assist or damping.
• Non-handed design means both slides in the pair are identical, so there is no left-right sorting on the bench.
• Zinc finish on cold-formed steel provides standard indoor corrosion resistance in a functional, low-profile appearance.
• Poly-Pack packaging delivers the pair ready to install, with mounting hardware included.

Where the Extra Inch Pays Off

A standard full-extension slide brings the drawer box to the cabinet face. The 8405 goes one inch further. Under a countertop overhang, that extra travel exposes the rear contents that would otherwise stay hidden. The same advantage applies to cabinets with a deep face frame, where the frame itself eats into accessible travel on a conventional slide. Drawers holding small tools, condiments, or rolled items at the back benefit most, since those contents are the ones most likely to stay buried on a full-extension-only slide. The hold-in detent works alongside the over-travel: once pushed shut, the drawer stays put rather than rebounding from a firm close.

Steel Construction and Zinc Finish

The 8405 is built from cold-formed steel with a zinc electroplate finish. Zinc is the workhorse finish in this segment: it protects the steel members through years of indoor cycling, requires no maintenance, and keeps a neutral appearance alongside white, almond, or natural wood cabinet interiors. The slide sits beside the open drawer box and is visible in use, so the finish choice matters in lighter-colored installations. Zinc reads as a clean metallic silver that blends without drawing attention. This is not a finish for wet, outdoor, or high-humidity environments; it is rated for dry indoor cabinetry.

Fitting This Slide to Your Project

The 8405 is a practical choice for kitchen cabinet shops, remodelers, and contractors installing drawers beneath countertops with a standard overhang. Designers specifying frameless or face-frame cabinetry where drawer access is a priority will find the over-travel removes a common complaint about rear contents. The 1/2 inch side clearance per side is the same as the rest of the KV 8400 line, so the drawer box sizing formula does not change if you are replacing or upgrading full-extension 8400-series slides with over-travel 8405s. In face-frame cabinets, the slide requires rear mounting support at the back; matching KV rear mounting brackets are sold separately and are series-specific. The 8405 is not the right choice where a detent is unwanted and a plain free-sliding or soft-close motion is preferred — for those applications, other slides in the 8400 family fit the same opening.

A Zinc Slide Built to Keep Drawers Where They Belong

The KV 8405 in zinc gives you over-travel access, a stay-closed detent, and a proven 100 lb rating in a non-handed pair that installs without fuss — a straightforward upgrade wherever a standard full-extension slide leaves the back of the drawer just out of reach.
