KV8150 18" 3/4 Extension Hold-In/Hold-Out Ball Bearing Keyboard Slides, Unhanded Side Mount Zinc Poly-Pack - 8150P 18
Description
Knape And Vogt 18 Inch Keyboard Slides For Trays
Knape and Vogt 18 inch keyboard slides give a 3/4 extension action, so a keyboard tray moves out for use while staying close enough to the cabinet for controlled reach in tight workstations. The 8150P 18 side mount design places the slides on the cabinet sides, keeping the underside of the tray clear for other hardware layouts. Ball bearing construction supports smooth travel, which helps frequent in-and-out use feel consistent over time. Hold-in and hold-out functions stabilize the keyboard tray at each end of travel, so the tray resists drifting during typing or when pushed fully back under the work surface. The slides are unhanded, so the same members fit left and right sides, simplifying layout and reducing part variation on repeat jobs.
Key Keyboard Slide Details That Aid Layout
- The 3/4 extension travel supports comfortable access to the keyboard while keeping the tray partly supported in the cabinet, which helps when designing shallower desks or casework with limited depth.
- Side clearance of 1-5/8 inch outboard and 5/8 inch inboard defines the required space around the tray, giving clear numbers for setting cabinet opening width and locating tray sides during fabrication.
- Height adjustment from 2-11/32 inch to 3-11/16 inch lets the mounting brackets shift vertically, which helps match the tray position to different work surface thicknesses and ergonomic targets across projects.
- Unhanded side mount slides place the same slide parts on both sides of the tray, simplifying inventory and helping streamline installation steps on multi-station or repeat commercial builds.
- The anochrome finish provides a uniform metallic appearance on the slide members, supporting a clean look on exposed or semi-exposed under-desk installations where hardware visibility matters.
Installation And Mounting Details For 8150P 18
The 8150 Series uses side mount brackets that adjust to seven different heights, giving defined detent positions when dialing in tray elevation relative to the work surface. These mounting brackets can be reversed for inboard or outboard mounting, so the installer can choose whether the slide sits closer to the cabinet wall or closer to the tray side to match existing casework geometry. The recommended fasteners are #8 x 5/8 inch Phillips pan head screws, which pair with the slide holes and bracket design to create a consistent mounting pattern along the cabinet and tray members.
Using 3/4 Extension Keyboard Slides In Desks
Where These Keyboard Slides Are Typically Used
The Knape and Vogt 8150P 18 keyboard slides are designed as side mount slides for keyboard trays under desks, counters, or work surfaces where a 3/4 extension motion is appropriate. The specified 18 inch length suits trays sized for standard keyboards in many office or workstation layouts, using the side clearance dimensions to define the opening in the surrounding cabinet. Adjustable height from 2-11/32 inch to 3-11/16 inch gives range to position trays under laminate, wood, or composite tops of varying thicknesses while keeping a comfortable typing height. The hold-in feature prevents keyboard tray bounce back when the tray is stored, which supports controlled stowing in tight knee spaces or shared work areas.
Details That Support Smooth Motion And Repeatable Fit
The ball bearing construction of the 8150 Series slide supports smooth drawer member travel, which helps keyboard trays move in and out with consistent resistance during regular use. The track member quickly disconnects using a positive lever release, so the tray section can be separated from the cabinet member during installation or adjustment, allowing the installer to mount or reposition the tray without the full assembly in the way. Mounting brackets that adjust to seven different heights create repeatable mounting points, which helps maintain the same tray position across multiple desks in a run. Brackets that can be reversed for inboard or outboard mounting provide flexibility around obstacles or side panels, letting the installer adapt to different casework designs while still using the same 8150P 18 slide set.
Common Questions About 8150P 18 Keyboard Slides
What does 3/4 extension mean on these slides?
The 3/4 extension keyboard slide 18 inch design lets the tray travel about three-quarters of its length out of the cabinet, supporting keyboard access while keeping more of the tray supported inside.
How do the adjustable mounting brackets help installation?
The adjustable height keyboard slide brackets offer seven vertical positions, so the tray height can be set precisely under different work surfaces while maintaining consistent alignment between desks.
What is the purpose of the hold-in and hold-out features?
The hold-in and hold-out features on these hold-in hold-out keyboard slide units help keep the tray stable when fully stored or fully extended, reducing unwanted drifting during everyday use.
How does the positive lever release aid setup?
The track member positive lever release lets the tray section disconnect quickly, so the cabinet and tray members can be handled separately during mounting, alignment, or removal.
What side clearance is required for these keyboard slides?
These slides use side clearance of 1-5/8 inch outboard and 5/8 inch inboard, giving fixed dimensions for cabinet opening and tray width planning during casework design.
What does anochrome finish mean for this slide?
The anochrome finish keyboard slide surface provides a uniform metallic appearance on the slide members, supporting a consistent look on projects where hardware edges may be visible.
Selecting The Right 18 Inch Keyboard Slide
The Knape and Vogt 18 inch keyboard slides 8150P 18 pair 3/4 extension, ball bearing travel, and unhanded side mounting for under-desk keyboard trays. Side clearance, adjustable mounting height, and reversible brackets give clear layout parameters for building or retrofitting casework. When an 18 inch, 3/4 extension, hold-in/hold-out, anochrome-finished side mount keyboard slide matches the planned tray size and cabinet geometry, this 8150 Series model provides defined dimensions and mounting features for consistent workstation installations.
