Zinc Finish And 1-Inch Over-Travel Built Into One Self-Close Slide

This is a 20 inch over-travel self-close ball bearing drawer slide from Knape and Vogt's 8419 series, rated 100 lb per pair, with a zinc finish and a spring-close mechanism that pulls the drawer fully shut after each use. The slide travels 1 inch past full extension, giving the drawer that extra reach past a countertop overhang or deep face frame.

Key Features

• 1-inch over-travel carries the drawer beyond full extension, clearing counter overhangs and deep face frames so rear contents are reachable.
• Self-close spring catches the drawer within the capture zone and pulls it fully shut without damping.
• 100 lb weight capacity per pair handles a loaded kitchen or utility drawer with room to spare.
• Zinc finish provides standard indoor corrosion resistance on a slide that blends into most cabinet interiors.
• Non-handed steel construction means the same slide fits either side of the drawer, simplifying bench sorting and installation.
• Bulk-Pack packaging keeps per-unit cost down for shops installing multiple drawers at once.

Where Over-Travel and Self-Close Work Together

Over-travel earns its keep when the cabinet sits beneath a countertop overhang or behind a substantial face frame. At full open, the drawer pushes 1 inch past the slide's nominal length, bringing the back of the box into clear reach instead of leaving it hidden under the lip. That extra inch makes a real difference in a deep kitchen base or a work-surface drawer where the installed position cuts into normal extension.

The self-close spring adds a practical layer in the same settings: push the drawer to within its capture zone and the spring finishes the job. It is an undamped close — the spring pulls the drawer home positively, which is distinct from a soft-close damper. There is no cushioning on the final travel, so the close is audible. For installations where a quieter close matters, look at the FR 5001 soft-close series instead. For drawers that simply need to stay shut, the self-close spring is reliable and maintenance-free.

Steel, Zinc, and What That Means for the Install

The slide is cold-formed steel with a zinc electroplate finish. Zinc is the working standard for side-mount ball bearing slides in cabinetry: it handles the indoor humidity cycles of a kitchen or shop without rusting, and it blends with painted or white-melamine interiors without drawing attention. This is not a decorative finish — it is a protective one. The zinc members are visible beside the open drawer box, which is normal for a side-mount slide.

The 1/2 inch side clearance requirement is standard for this class of slide. Build the drawer box 1 inch narrower than the cabinet opening to leave 1/2 inch clearance on each side. The design is non-handed, so both slides in a pair are identical — no left-right sorting on the bench.

The Right Drawer for This Slide

The 8419 series fits kitchen base drawers, utility cabinets, and work-surface drawers where the installed position eats into normal extension travel. It suits shops specifying a consistent side-mount platform across a production run: the Bulk-Pack format keeps inventory simple for cabinet shops installing this slide across multiple boxes. At 100 lb per pair, it covers everyday kitchen and shop drawer loads. For file drawers or heavier storage, move up to the 150 lb class 8500 series.

A Dependable Platform for Production Cabinet Work

The KV 8419 in zinc gives production shops a self-close, over-travel slide that installs fast, fits either side of the drawer, and handles the load ranges of everyday cabinetry — all in a bulk format sized for shops that measure slides by the carton, not the pair.
