The Knape and Vogt 8150 Series is a 16 inch, 3/4-extension side-mount ball bearing keyboard slide finished in Ebony Black, designed for pull-out keyboard trays and work surfaces where the hardware color needs to blend with dark or black-finished cabinetry. It holds both open and closed on demand, so the tray stays put whether you are typing or tucked away.
A keyboard tray has two jobs: stay open while you work, and stay closed when you do not. Plain slides with no detent drift in both directions — the tray creeps out on a slight floor angle, or bounces back open after you push it closed. The 8150's combined hold-in and hold-out detents solve both problems with the same mechanism. Pull the tray to full extension and the hold-out catches it there. Push it closed and the hold-in keeps it shut until you pull again. There is no soft-close damper and no spring assist — just positive mechanical engagement in both positions.
The slide is cold-formed steel with an Ebony Black finish that stands out from the zinc-plated standard in this line. Where the surrounding cabinetry, desk structure, or tray platform is dark or black, a zinc slide reads as a visual mismatch at the side of the open tray. The black finish keeps the hardware from drawing attention. Ball bearings run in full-length steel raceways for consistent, low-friction travel cycle after cycle. This is a functional indoor finish — it is not a decorative or stainless coating, and these slides are designed for dry interior applications.
The 8150 Series in black is the right choice for home offices, built-in desk units, media consoles, and workstations where the keyboard tray pull-out is visible when open and the finish matters. Cabinet shops building dark-finish or black-painted desk components can spec this slide to match without a custom finish order. At 75 lb capacity per pair and 3/4 extension, it is sized specifically for keyboard-and-mouse work surfaces rather than general storage drawers — the travel brings the tray to a natural typing position without requiring the full depth of the cabinet interior. Sold as a poly-pack pair.
Hold-out is a detent that catches the tray at the fully open position and keeps it there until you push it closed. Hold-in is a detent that keeps the tray closed until you pull it open. Both release with a normal push or pull — neither is a positive lock.
No. The 8150 is a standard-motion slide with hold-in and hold-out detents. There is no damper, so closing is not slowed or cushioned.
This is a 3/4-extension slide — the tray opens roughly three-quarters of the 16 inch slide length. The rear portion of the tray stays inside the cabinet at full open, which is the standard travel for keyboard tray applications.
No. The slide is non-handed, so both pieces in the pair are identical and either one fits either side of the tray.
Side-mount slides in face-frame cabinets need rear support at the back of the slide. Add matching rear mounting brackets for this series — brackets are sold separately and are series-specific.
When the workstation is dark and the hardware needs to disappear, the 8150 Series in Ebony Black delivers the hold-in/hold-out function of a dedicated keyboard slide in a finish that keeps up with the rest of the build.
