KV8525 20" Over Travel Hold-in anti-rebound Ball Bearing File Drawer Slides, Unhanded Side Mount Zinc Poly-Pack - 8525P 20

Knape And Vogt 8525 File Drawer Slide Performance

Knape and Vogt 20 inch over travel file drawer slide describes a 20 inch side mount ball bearing file drawer slide from the KV 8525 Series that supports file drawers needing extended opening. The 1-1/4 inch overtravel lets the drawer extend past full length, which brings hanging files and rear contents forward for easier access in casework or cabinetry. The side mount design places the slide on the cabinet side, which suits traditional file drawer construction where space beside the drawer box is available. A hold-in feature to prevent bounce back keeps the drawer from drifting open after closing, which helps cabinets stay shut in offices, shops, and mobile environments. Positive in/out stops define travel limits, which helps protect drawer fronts and face frames from impact at full extension or full close. Progressive movement on ball bearings supports smooth motion along the entire travel path, which helps drawers feel consistent under normal loading.

Key Drawer Slide Details That Support The Job

• The side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the required gap between drawer and cabinet, which guides sizing of the drawer box for proper slide engagement.
• The height of 3-51/64 inch including the quick disconnect rail gives the vertical envelope of the slide, which matters when stacking drawers or working within shallow cabinet openings.
• The 32 mm pattern provides a hole layout based on the 32 mm system, which helps align slide mounting with cabinet rows drilled on that standard for faster, repeatable installation.
• The non-handed quick disconnect drawer members allow the same slide to work on either side and separate from the drawer, which simplifies layout and drawer removal during construction or service.
• The metal ball retainer holds 3 bearings per inch for smooth and quiet motion, which helps drawers open and close with less noise in office and residential settings.
• The recommended fasteners of #7 x 5/8 inch Phillips pan head anchor the slide to cabinet and drawer, which supports a consistent mounting method when matching the specified screws.

Side Mount Installation And Fit Considerations

The side mount configuration places the Knape and Vogt 8525 Series slide between the cabinet side and drawer side, which sets the basic construction method for the file drawer. The specified side clearance of 1/2 inch plus 1/32 inch minus 0 inch per side defines the target drawer width, which helps fabricators size drawer boxes for smooth travel without excess play. The height of 3-51/64 inch including quick disconnect rail establishes the minimum vertical space when planning drawer spacing in tall cabinets. Direct access mounting holes give installers reachable screw locations along the slide, which can reduce effort during installation in deep or narrow casework. The 32 mm pattern allows the slide to line up with system holes, which supports jig drilling or CNC patterns already based on that standard.

Where This 20 Inch Over Travel Slide Fits Best

The Knape and Vogt 20 inch over travel file drawer slide 8525P 20 suits file drawer applications where access to the back of the drawer is important, because the 1-1/4 inch overtravel brings rear folders beyond the cabinet face. The side mount drawer slide format fits casework built for lateral or vertical file drawers using side-mounted runners, which is common in office furniture, built-in cabinetry, and shop storage. The unhanded side mount design means the same member can mount on either left or right side, which can simplify inventory for installers handling multiple cabinets. The available Anochrome finish defines the surface treatment on the slide, which sets the visual match to other zinc-colored hardware in a project. The high-strength steel alloy construction provides a metal slide body, which supports rigid mounting surfaces for the ball bearings under typical file drawer loads.

Details That Help Repeatable Motion And Service

The hold-in feature to prevent bounce back keeps the drawer seated when closed, which reduces nuisance openings on file drawers that are frequently used during the day. Positive in/out stops define the opening and closing endpoints, which helps maintain predictable travel and reduces the chance of overrunning the slide travel. Progressive movement on ball bearings moves the members together rather than in stages, which creates a smoother feel from closed to fully extended. The metal ball retainer holding 3 bearings per inch maintains a dense bearing layout, which supports motion that remains quiet and controlled over the slide length. Non-handed quick disconnect drawer members let the drawer be removed from the cabinet, which simplifies finishing, adjustment, and future service. The secondary QD lock referenced in the description adds another element to the disconnect system, which supports more secure engagement between drawer member and cabinet member during normal operation.
