KV 8150 12" Hold-In/Hold-Out Side Mount 3/4 Extension 75 lb Ball Bearing Keyboard Slide, Poly-Pack, Black, 8150P EB 12

Black Ball Bearing Keyboard Slides That Stay Where You Put Them

The Knape and Vogt 8150 Series is a 12 inch side-mount ball bearing keyboard slide in Ebony Black, rated 75 lb per pair, with a hold-in/hold-out detent that keeps the tray closed when stowed and fully open while in use. It is the right choice when the slide hardware needs to disappear against a dark cabinet interior or a black-finished desk frame.

Key Features

• Hold-in/hold-out detent catches the tray in both the closed and fully open positions, so it stays put without a latch or your spare hand.
• 3/4 extension brings the tray the majority of the way out of the cabinet — the rear portion of the slide stays inside the opening at full travel.
• 75 lb rating per pair handles a keyboard, wrist rest, and peripheral comfortably.
• Ball bearing construction on a steel slide delivers smooth, consistent travel across the full range of motion.
• Ebony Black finish matches dark cabinetry and desk frames without the visual contrast of bare zinc hardware.
• Non-handed design means one part number fits both sides — no left or right to sort before installation.

Where the Hold-In/Hold-Out Detent Earns Its Keep

A keyboard tray that creeps closed mid-task or drifts open under desk traffic is a daily frustration. The 8150's dual detent solves both problems at once: push the tray fully closed and the hold-in catches it; pull it to the open position and the hold-out locks it there until you push it back. No spring assist, no damper — the tray simply stays wherever you deliberately put it. That makes this slide well suited to standing desks, credenzas, and workstations where the tray is stowed for long periods and then deployed fully open for use.

Finish and Construction

The slide is cold-formed steel with an Ebony Black finish. Black hardware is the natural choice when the desk or cabinet interior is dark-stained, painted, or finished in black melamine — the slide recedes visually rather than drawing attention to itself beside an open tray. Steel ball bearings run in formed raceways for smooth travel under load. This is an indoor slide; the finish is not rated for wet or exterior environments.

Who This Slide Is For

The 8150 Series in Ebony Black is a practical fit for office furniture builders, commercial millwork shops, and cabinet makers producing desks, credenzas, and workstations with integrated keyboard storage. The 12 inch length suits standard keyboard tray depths. Designers specifying dark-finished or black-painted casework will find the color match far cleaner than zinc on an open tray. The poly-pack format keeps pairs organized on the bench during a multi-unit build. For face-frame construction, rear mounting brackets are required and sold separately — the brackets are series-specific, so confirm compatibility with the 8150 before ordering.

The Right Slide for the Right Cabinet

When the build calls for dark hardware and a keyboard tray that stays put at both ends of its travel, the KV 8150 in Ebony Black delivers a clean, purpose-built solution without improvising with a standard cabinet slide.
