KV8520 16" Full Extension Hold-in anti-rebound Ball Bearing File Drawer Slides, Unhanded Side Mount Zinc Poly-Pack - 8520P 16

Knape And Vogt 16 Inch Full Extension File Slide

Knape and Vogt 16 inch full extension file drawer slide gives a file drawer full access to its length, so folders and contents are reachable without shifting the cabinet. The 8520 series design uses progressive movement on ball bearings, so the file drawer opens and closes in a smooth, continuous motion that feels controlled under load. A hold-in feature provides anti-rebound action, so the drawer stays closed against the case instead of drifting out. Positive in and out stops define the travel limits, helping protect the slide and the cabinet from over-travel stress. An extended Z-plate built from high-strength steel alloy supports the file drawer structure, which matters on deeper drawers that carry heavier filing loads. The slide is unhanded for side mounting, so the same member profile works on either side of the drawer, simplifying layout and keeping pairs consistent across multiple units.

Key 8520P 16 Details That Support File Storage

• The specified side clearance is 1/2 inch plus 1/32 inch minus 0 each side, which sets a clear drawer-to-cabinet sizing window so casework can be machined for a predictable lateral fit.
• The overall height is 3-51/64 inch including the quick disconnect rail, so the slide supports file drawer side panels sized for hanging files while leaving room to plan vertical spacings in the cabinet.
• The 32 mm pattern is present, so the slide aligns with system-drilled cabinet sides that follow 32 mm construction, speeding layout and reducing separate measuring steps on production runs.
• The metal ball retainer holds 3 bearings per inch, so the moving members ride on closely spaced balls, which supports smooth and quiet motion on file drawers that are opened and closed repeatedly.
• The available finish is Anochrome, so the steel members have a protected surface that also presents a consistent metallic appearance inside casework where the hardware remains visible.

Mounting, Clearance, And Fastener Choices For 8520

This 8520 series member is a side mount drawer slide, so it fastens to the cabinet sides and the drawer sides in a parallel arrangement that suits typical file drawer construction. The side clearance specification of 1/2 inch plus 1/32 inch minus 0 each side defines the necessary gap between the drawer and cabinet, so layout can be dimensioned directly from the slide data rather than trial fitting. Recommended fasteners are #7 x 5/8 inch Phillips pan head screws, so hole sizing and driver selection can be planned around this screw format during shop or onsite installation. Direct access mounting holes are provided, so screws can be driven through the members without disassembly, which streamlines mounting when working inside deeper cabinets.

How The KV 8520P 16 Works In File Cabinets

Where This Side Mount File Drawer Slide Fits

The 8520P 16 full extension file drawer slide is part of the Knape and Vogt 8520 series, so it is intended specifically for file drawer applications where full access to folders is important. Its side mount configuration suits cabinets with solid or panel sides that accept screw mounting along the length of the slide, allowing the cabinet interior to stay clear beneath the drawer. The height of 3-51/64 inch including the quick disconnect rail supports drawers built to file-drawer proportions, so the hardware aligns with taller sides common in letter or legal file storage. The unhanded quick disconnect drawer members allow the same part to serve both left and right sides, which simplifies ordering and speeds assembly when fitting multiple drawers in a bank of casework. The presence of a 32 mm pattern aligns this slide with case construction that follows system-hole drilling, so it integrates into frameless cabinet runs without extra layout steps.

Why These 8520 Features Support Repeatable Results

The hold-in feature with anti-rebound action helps the file drawer stay seated in the cabinet when closed, so drawer faces remain aligned in a run and are less likely to creep outward after use. Positive in and out stops define the limits of travel, so the drawer does not overrun the slide members, which helps maintain consistent performance across repeated openings. Progressive movement on ball bearings means both slide members move together through the stroke, giving a smooth feel throughout the extension that supports controlled handling of heavier file loads. The metal ball retainer holding 3 bearings per inch distributes support along the travel path, so point loads are reduced and motion stays quiet in office or commercial environments. The extended Z-plate and high-strength steel alloy construction provide structural support behind the drawer members, which matters when file drawers are loaded near capacity and still need consistent tracking. Direct access mounting holes support accurate screw placement, so installers can fasten members in line with the design pattern and repeat the same geometry across many cabinets.

Common Questions About The 8520P 16 File Slide

Selecting The Right 8520P 16 For File Projects

The 8520P 16 full extension file drawer slide from Knape and Vogt combines side mount installation, defined 1/2 inch side clearance, and a 3-51/64 inch height to match typical file drawer proportions. The 32 mm pattern supports frameless or system-based cabinet layouts, while progressive movement on ball bearings and a hold-in feature support controlled operation in daily use. When a file cabinet or casework run calls for a 16 inch full extension travel with defined clearances, this 8520 series member provides the mounting and movement characteristics needed for consistent, repeatable drawers.
