8250 Variable Height Pencil Drawer Slides For Desks

8250 variable height pencil drawer slides from Knape and Vogt are 3/4 extension, under-mount slides designed for pencil drawers and keyboard-style trays, so they support shallow desk storage where knee clearance matters. The slides are part of the Pencil Drawer and Keyboard Tray Slides class, which supports light, frequent-use drawers under work surfaces. An under-mount design places the hardware beneath the drawer, which keeps the sides clear for narrow tray construction in office or shop environments. The stay-close function holds the drawer shut at the back of travel, which helps keep trays from drifting out during everyday use. An adjustable drop height from 2-11/32 inches to 3-11/16 inches lets the installer set drawer position relative to the work surface, which helps balance leg room, clearance for contents, and alignment with surrounding cabinetry.

Key Working Details Of These Undermount Slides

• The 3/4 extension travel limits how far the drawer projects, which helps keep shallow pencil drawers stable and reduces leverage on the slides when mounted under desks or counters.
• The under-mount configuration carries the drawer from below, which leaves the drawer sides unobstructed and can simplify building low-profile trays for writing instruments or small tools.
• The stay-close feature holds the drawer in the closed position, which reduces unwanted opening from vibration or user contact and helps keep narrow trays neatly stowed under the work surface.
• The drops adjust between 2-11/32 inches and 3-11/16 inches in 7/32 inch increments, which gives installers seven fixed mounting heights to match drawer depth and achieve consistent reveals across multiple workstations.
• The slides use outboard side clearance of 1-5/8 inches per side and inboard side clearance of 17/32 inch per side, which defines the space needed around the assembly when designing casework and positioning adjacent components.
• The Anochrome finish provides a uniform metallic look on the slides, which supports a professional appearance wherever hardware is visible at the underside of desks or counters.

Under-Mount Installation And Height Adjustment Details

These Knape and Vogt 8250 slides are under-mount units for pencil drawers and keyboard trays, so they attach beneath the drawer box and related support structure rather than at the sides. The mounting brackets adjust through seven heights between 2-11/32 inches and 3-11/16 inches, in 7/32 inch increments, which allows installers to set a consistent drop from the work surface across multiple locations. A defined side clearance of 1-5/8 inches outboard and 17/32 inch inboard per side provides layout guidance when spacing structural members, and it helps avoid interference with nearby components. Recommended fasteners are #7 x 1/2 inch Phillips Pan Head (WW44190), which match the slide design and support a secure installation into typical desk and cabinet materials.

Using These Slides In Desk And Tray Projects

Where These Pencil Drawer Slides Perform Best

Knape and Vogt 8250 variable height pencil drawer slides are designed for pencil drawers and keyboard tray style applications, so they align well with desks, counters, and workstations that need shallow storage directly beneath the top. The slides use an under-mount layout, which locates the moving members below the drawer and helps preserve side clearance above leg space. Side clearance of 1-5/8 inches outboard per side influences the structural framing around the drawer, guiding where rails or panels can be placed without binding the movement. The 17/32 inch inboard clearance per side affects how the internal supports are arranged, which can streamline planning for modest-width trays. An adjustable drop between 2-11/32 inches and 3-11/16 inches lets installers tune the drawer height for different top thicknesses while keeping comfortable legroom. The Anochrome finish complements commercial and residential casework where exposed underside hardware may be seen when seated.

Details That Support Repeatable Drawer Alignment

The 8250 variable height pencil drawer slides include mounting brackets that shift through seven fixed positions from 2-11/32 inches to 3-11/16 inches, in 7/32 inch steps, which supports consistent drawer reveals across multiple units on a run of desks. Having discrete increments simplifies layout, because installers can reference known positions rather than measuring from scratch at every opening. The 3/4 extension movement limits projection, which helps keep the center of gravity closer to the cabinet face and supports smoother operation in long-term use. A stay-close feature holds the drawer in the retracted position, limiting unintended opening when users brush against the front. The anti-bounce feature works with this function to resist oscillation at travel limits, which can reduce rattle in frequently used office or shop environments. Made in the USA, these slides align with projects that specify domestic hardware sources for their drawer movement components.
