8250 Variable Height Pencil Drawer Slides, 3/4 Extension, Under-Mount, Stay-Close, Anochrome, 18", Polybag

8250 Variable Height Pencil Drawer Slides For Desks

8250 variable height pencil drawer slides give you an under-mount, stay-close slide solution for shallow pencil drawers and trays where clean appearance and controlled travel matter. This Knape and Vogt 8250P 18 model is part of the Pencil Drawer and Keyboard Tray Slides class, so it is built specifically around low-profile desk and work-surface applications instead of deep cabinet drawers. The 3/4 extension travel keeps a pencil drawer within controlled reach while limiting over-travel, which helps maintain stability for light office contents. An under-mount layout keeps hardware below the drawer box, which supports a cleaner side view on finished furniture and casework. The stay-close function keeps a light drawer from drifting open, which is useful on desks that see regular movement. An anochrome finish provides a neutral appearance that integrates smoothly with typical office and shop hardware finishes.

Key Working Details Of These 8250 Slides

• Knape and Vogt model 8250P 18 establishes a consistent reference when matching to prints or existing installs, which helps maintain uniform hardware across multiple stations or rooms.
• The 18 inch length suits typical pencil drawer and shallow tray depths, so it aligns well with common desk and work-surface proportions without overextending the slide travel.
• The product is described as made in the USA, which matters on projects that specify domestic manufacturing for sourcing standards or job documentation.
• Side clearance of 1-5/8 inch per side outboard controls where the outer members sit in relation to the desk opening, which helps with planning rail locations and drawer width.
• Side clearance of 17/32 inch per side inboard defines the space around the moving drawer member, which is important when sizing a pencil drawer box or tray for smooth action.
• Classification under Drawer Slides and Slides, Undermount confirms that this slide is intended for under-mount drawer applications, guiding how it fits within a hardware schedule.

Mounting And Adjustment Details For Installation

The mounting brackets on this slide adjust to seven heights from a side height drop of 2-11/32 inch to 3-11/16 inch in 7/32 inch increments, so you can fine-tune the drawer position under different tops or rails while keeping a repeatable step between settings. This variable height range supports fitting pencil drawers beneath thicker tops where clearance is tight, without redesigning the box. The recommended fasteners are #7 x 1/2 inch Phillips pan head screws (WW44190), which tells you the shank size and head style these brackets and slide members are drilled to accept. Using that screw size keeps the fastener interface within the intended bearing area of the hardware holes, supporting consistent clamping and slide alignment along the run.

Using 8250 Pencil Drawer Slides In Real Projects

Where These Pencil Drawer Slides Are Applied

This Knape and Vogt 8250 variable height pencil drawer slide is specified for pencil drawers and keyboard trays, so it aligns well with office desks, workstations, and shop benches that need a shallow storage or typing surface directly under the work top. The 3/4 extension rating means the drawer or tray projects partway out of the opening, which suits light-use items such as pens, small tools, or a low-profile keyboard while keeping weight closer to the cabinet face. Because it is an under-mount slide, visible hardware along the drawer sides is minimized, which helps when the desk or workstation design leaves the drawer sides exposed to view. The anti-bounce feature listed in the product description works to resist a light drawer rebounding after closing, which is significant on smooth tops where small motions can otherwise nudge a drawer back open.

Details That Support Repeatable Fit And Performance

The overall drop height range of 2-11/32 inch to 3-11/16 inch stated for the side height, with 7 distinct positions in 7/32 inch increments, gives installers a predictable adjustment pattern for aligning multiple pencil drawers along a shared run of casework. This pattern helps keep reveal lines consistent from station to station without measuring each bracket setting from scratch. The stated 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, so casework and drawer box dimensions can be set to those numbers and repeated across similar cabinets. The note that there is no 32 mm pattern tells you that the slide is not drilled to the European 32 mm system, which matters when laying out mounting holes on custom casework. The anochrome finish provides a uniform, light-metal appearance that blends with common drawer hardware palettes, which is helpful on open or glass-fronted furniture where hardware color can stand out.
