8250 Variable Height Pencil Drawer Slides, 3/4 Extension, Under-Mount, Stay-Close, Anochrome, 20", Polybag

8250 Variable Height Pencil Drawer Slides For Desks

8250 variable height pencil drawer slides from Knape and Vogt are 20 inch, 3/4 extension, under-mount slides designed for pencil drawers and keyboard tray applications. The under-mount design supports desk and workstation layouts where clear side access is important, while the 3/4 extension travel gives enough reach into the drawer without overextending the slide. The stay-close feature holds the drawer closed at the end of travel, which helps drawers remain shut in everyday use. These slides are part of the Pencil Drawer and Keyboard Tray Slides product class, so they align with shallow desk drawers rather than deep storage drawers. The anochrome finish on the slides provides a neutral metal appearance that matches common office and shop environments. Model 8250 is made in the USA, giving shops a clearly identified domestic source when specifying hardware.

Key Working Details That Support Drawer Layouts

• Side clearance of 1-5/8 inch per side outboard and 17/32 inch per side inboard sets the required spacing for the slide, which helps installers size pencil drawer boxes and openings to avoid side binding.
• An overall drop height range from 2-11/32 inch to 3-11/16 inch defines where the drawer sits below the mounting surface, which helps coordinate drawer thickness with knee clearance and underside obstructions.
• Mounting brackets that adjust in 7/32 inch increments give seven discrete height positions, which allows repeatable settings across multiple desks or stations without custom shimming for each installation.
• The anti-bounce feature stabilizes the drawer movement at the end of travel, which helps drawers stay seated against the stay-close position during normal use in offices or shops.
• The anochrome finish provides a consistent metal surface, which suits installations where the slides may be visible from below or alongside open desks and workstations.

Under-Mount Installation And Height Adjustment Details

These Knape and Vogt 8250 under-mount slides position beneath the pencil drawer or keyboard tray, which keeps the hardware away from the drawer sides and allows narrow, low-profile drawer construction. The side clearance specification of 1-5/8 inch per side outboard and 17/32 inch per side inboard defines the offset relationship between the supporting structure and the moving drawer member, so installers can plan their side panels and intermediate supports around those dimensions. The adjustable mounting brackets set the overall drop height from 2-11/32 inch to 3-11/16 inch, in 7/32 inch increments, which lets installers align the drawer front relative to the desktop while maintaining consistent clearances. The recommended fasteners are #7 x 1/2 inch Phillips pan head screws (WW44190), so the slide holes are sized to work with that screw pattern.

Using 8250 Slides In Pencil Drawer Projects

Where These Pencil Drawer Slides Are Applied

The 8250 variable height pencil drawer slides are used in pencil drawer and keyboard tray installations where an under-mount slide is preferred. The 20 inch length supports drawers sized for standard desk widths, giving a balance between reach and available space under the top. The side clearance requirement of 1-5/8 inch per side outboard and 17/32 inch per side inboard means these slides fit projects where the designer can allocate that clearance in the desk or cabinet structure, such as custom office furniture, workstations, or shop benches with shallow drawers. The adjustable mounting brackets that span from 2-11/32 inch to 3-11/16 inch overall drop height let installers position the drawer beneath a variety of top thicknesses while aiming for consistent knee comfort in seated work areas.

Details That Support Consistent Drawer Performance

The mounting brackets on the Knape and Vogt 8250 slides adjust in seven steps, each 7/32 inch apart, covering an overall drop height from 2-11/32 inch to 3-11/16 inch. This stepped adjustment allows installers to repeat the same bracket setting across multiple drawers, which supports uniform reveal and clearance without measuring each location from scratch. The 3/4 extension travel controls how far the pencil drawer or keyboard tray moves out from the desk, which helps keep the slide within its designed working range while giving users access to contents in normal seated positions. The stay-close feature at the end of travel holds the drawer shut, which reduces unintended opening in day-to-day use. The anti-bounce feature manages drawer movement as it reaches the closed position, which helps the drawer settle against the stay-close point instead of rebounding outward. The specified side clearances of 1-5/8 inch per side outboard and 17/32 inch per side inboard define the working envelope of the slide members, which guides cabinetmakers in sizing the drawer and support structure so the slide can run smoothly over its service life.
