Zinc-Finished Over-Travel Ball Bearing Slide for Drawers Behind Countertop Overhangs

The Knape and Vogt 8405 Series is a 24 inch side-mount ball bearing drawer slide in bright zinc finish, rated 100 lb per pair, with 1 inch of over-travel that carries the drawer past full extension. It is built for drawers that sit beneath countertop overhangs or deep face frames, where standard full-extension slides leave the back of the drawer just out of reach.

Key Features

• 1 inch of over-travel pushes the drawer member past the nominal 24 inch slide length, clearing overhangs so rear contents are fully accessible.
• 100 lb load rating per pair handles a well-loaded kitchen or utility drawer through daily use.
• Hold-in anti-rebound detent keeps the drawer firmly closed and prevents it from bouncing back open after a firm push.
• Steel ball bearings in full-length raceways deliver smooth, consistent travel on every pull.
• Non-handed design means the same slide fits the left and right sides of the cabinet — no sorting at the bench.
• Bright zinc finish provides standard indoor corrosion protection on a functional side-mount slide.

Where Over-Travel Pays Off

An over-travel slide earns its place when something in front of the cabinet eats into the drawer's opening clearance. A countertop overhang that hangs past the face frame, a thick applied end panel, or a deep decorative rail all create the same problem: a standard full-extension slide gets the drawer to the face of the cabinet, but the front lip of the countertop blocks access to the rear inch or two. The 8405's 1 inch of additional travel steps past that obstruction and puts the back of the drawer within reach without rebuilding the cabinet around it. It also suits shallow utility drawers in shop or garage cabinets where the full depth is needed for long-handled tools or oversized contents.

Zinc Finish and Construction

The slide members are cold-formed steel with an electroplated zinc finish. Zinc is the workhorse surface treatment for side-mount ball bearing slides — it protects against the light moisture and condensation common in kitchens and utility spaces, blends into most cabinet interiors without drawing attention, and holds up through years of indoor cycling. This is not a decorative finish and is not rated for outdoor or wet environments. For cabinetwork where the slide will be visible beside an open drawer, the neutral zinc tone reads as clean and professional without competing with the hardware on the drawer front.

Fitting This Slide to the Job

The 8405 is the right call when the drawer depth and load are in the standard kitchen and utility range — up to 100 lb per pair — and the installation has an overhang or recess that a plain full-extension slide cannot clear. The hold-in anti-rebound detent is a practical addition in busy kitchens or shop environments where drawers get pushed shut firmly; it stops the bounce-back without adding spring weight or a closing mechanism. This bulk-pack format is sized for shops and contractors ordering multiple pairs at once. The slide is non-handed and uses the standard 1/2 inch side clearance, so the drawer box is built 1 inch narrower than the cabinet opening. In face-frame cabinets, rear mounting brackets are required to support the back of the slide — these are sold separately and are series-specific to the KV 8400/8405 line.

Ready for the Overhang Problem

When the countertop or face frame gets in the way of a full drawer pull, the 8405 Series solves it cleanly — 1 inch of over-travel, a hold-in detent that stops bounce-back, and a zinc finish built for years of indoor service, all in a non-handed slide that ships in bulk quantity for the shop floor.
