KV 8157 14" Hold-In/Hold-Out Side Mount 3/4 Extension 75 lb Ball Bearing Keyboard Slide, Poly-Pack, Black, 8157P EB 14

14 Inch Black Keyboard Slide for Clean-Look Workstations and Desks

This is a 14 inch side-mount ball bearing keyboard slide from Knape and Vogt's 8157 series, finished in Black and rated 75 lb per pair. It features a combined hold-in and hold-out detent that keeps the tray parked in both the closed and fully open positions until intentionally moved.

Key Features

• Black finish blends with dark-finished cabinetry, painted steel frames, and modern laminate work surfaces where a zinc slide would stand out.
• Hold-In and Hold-Out detents lock the tray in the closed position and hold it fully open hands-free — no hunting for a latch while the keyboard is in use.
• 3/4 extension pulls the tray clear of the cabinet opening for comfortable typing reach without requiring the full interior depth of a full-extension slide.
• 75 lb weight rating per pair handles a keyboard, mouse, and accessories with margin to spare.
• Non-handed ball bearing design means both slides in the pair are identical — no left and right to sort on the bench.
• Poly-Pack packaging ships one pair per bag, ready for a single workstation installation.

Built for the Workstation, Not the Kitchen Drawer

A keyboard slide has different demands than a standard cabinet drawer slide. The tray needs to hold open while both hands type, stay shut when pushed in, and travel smoothly at low extension depth. The 8157's combined hold-in and hold-out detent handles both positions mechanically — push the tray in and the hold-in catches it; pull it out to full extension and the hold-out keeps it there. No extra hardware, no separate tray lock. At 3/4 extension, the tray travels far enough forward for a natural typing posture without requiring a deep cabinet opening behind it.

Steel Construction in a Finish That Stays Hidden

The slides are cold-formed steel with a Black finish — an intentional choice for installations where the slide will be visible alongside dark or painted surfaces. Under a Black or dark-stained desktop, a zinc slide draws the eye; this one doesn't. The finish provides standard indoor corrosion protection. These slides are for interior, dry-environment installations.

Where This Slide Fits Best

Choose the 8157 in Black for workstations, built-in desks, and home-office cabinetry with dark or Black hardware finishes. It also works well in commercial office furniture and reception counters where the hardware color coordinates with the overall design. The 14 inch length suits shallow pullout trays and compact desks where a longer slide would overhang the cabinet depth. Cabinet shops fitting out an office suite with Black drawer pulls and hinges can spec this slide to match without ordering a separate color program.
