KV 8157 16" Hold-In/Hold-Out Side Mount 3/4 Extension 75 lb Ball Bearing Keyboard Slide, Poly-Pack, Black, 8157P EB 16

Matte Black Finish, Built-In Hold for Both Positions

This is a 16 inch, 3/4-extension side-mount ball bearing keyboard slide from Knape and Vogt's 8157 series, rated 75 lb per pair, finished in black, with detents that hold the platform firmly at both the closed and fully open positions.

Key Features

• Black finish keeps the slide hardware low-profile against dark desk undersides and black laminate surfaces.
• Hold-in detent keeps the keyboard tray pushed in and flush until intentionally pulled — no drift or bounce-back.
• Hold-out detent locks the tray at the fully open position so it stays put hands-free while in use.
• Ball bearing construction delivers smooth, consistent travel on every pull, even under a loaded tray.
• Non-handed design means both slides in the pair are identical — no left/right sorting required at installation.
• 75 lb rating per pair covers a keyboard, monitor arm base, or other under-desk load well within the slide's capacity.

What the Hold-In/Hold-Out Detents Actually Do

Most slides let a platform drift. The 8157 does not. The hold-in detent catches the tray when pushed closed and keeps it there — even on an unlevel surface or in a busy workspace where the tray might otherwise slide back out on its own. The hold-out detent latches the tray at full open so both hands are free to type, adjust cables, or position a mouse. Neither position requires a latch or lever; a deliberate push or pull releases the detent naturally. That two-position control is what makes this series useful for keyboard applications specifically, where half-open is never the goal.

Steel Construction in a Working Black Finish

The slide members are cold-formed steel with a black finish that reads cleanly in any desk or millwork application where a zinc or anochrome slide would catch the eye. The finish is a functional, indoor-rated coating — not decorative powder coat — suited to the dry interior environment of office furniture and cabinetry. The 3/4-extension travel means the rear of the platform remains inside the cabinet or desk housing at full open, which is the expected behavior for keyboard platforms where a full-depth pull is unnecessary and often undesirable.

Keyboard Platforms, Under-Desk Trays, and Light Pull-Outs

The 8157 is built for keyboard and under-desk tray applications: the 16 inch length matches standard keyboard platform depth, the 75 lb per pair rating handles the combined weight of a keyboard, wrist rest, and accessories without using even a fraction of available capacity, and the hold-out detent makes hands-free use practical. The black finish pairs naturally with dark melamine interiors, furniture panels finished in espresso or black, and desk frames where a zinc slide would look out of place. Side-mount installation gives the platform rigid lateral support with 1/2 inch of side clearance per slide. This is a poly-pack SKU — one pair per pack, ready for a single station installation.

The Right Slide Stays Out of the Way

A keyboard tray that drifts open or drops shut mid-use is a daily annoyance. The 8157 in black holds where you put it, blends into dark desk interiors, and gives the tray a smooth, reliable pull every time — exactly what a platform slide should do.
