KV8500 28" Full Extension Hold-in anti-rebound Ball Bearing File Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 8500B 28

Knape and Vogt 28 Inch File Drawer Slide

Knape and Vogt 28 inch drawer slide defines this 28 inch full extension ball bearing file drawer slide as a side mount solution for projects that need full access to the drawer length. The slide belongs to the KV Model 8500 Series, so it matches installations already built around this series for consistent motion and fit. The unhanded side mount design lets the same member work on either side of the drawer, which simplifies planning and reduces part variation on the job. This slide is identified as product class Side Mount Drawer Slides, so it suits cabinet layouts that are already framed for side-mount hardware instead of undermount systems. It is made in USA, which gives shops a clear origin when projects specify domestic components. The slide uses ball bearing construction, so the movement stays smooth under file drawer loads where frequent opening and closing is part of everyday use.

Key 8500B 28 Features For File Drawers

• The full extension design lets the drawer travel the full 28 inch length, so files stored at the back can be reached without shifting front folders during normal access.
• Ball bearing construction with a retainer that holds 3 bearings per inch of race creates smooth and quiet motion, which matters in office settings where drawers are opened repeatedly throughout the day.
• The hold-in feature is designed to prevent bounce back, so when the drawer is pushed closed it stays shut rather than rolling slightly open, which helps keep file banks aligned and tidy.
• Positive in and out stops control travel at both ends of the stroke, helping prevent the drawer from over-traveling and stressing the cabinet or file frame during hard pulls.
• Factory-attached drawer release clips with quick disconnect drawer members speed up removal and reinstallation of the drawer, which saves time during cabinet installation, adjustment, or service work.
• The side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side sets a clear gap target, helping builders size drawer boxes to fit consistently on production runs.

Mounting And Dimensional Details For Installers

This 28 inch length slide is set up for side mount use, so it bolts to the cabinet sides in systems already framed for Side Mount Drawer Slides. The stated side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the total drawer-to-cabinet gap, letting installers size drawer widths so the slides load without racking. The height of 3-51/64 inches including the quick disconnect rail gives a fixed profile that must fit within the cabinet opening, so casework can be laid out so the slide clears internal stretchers or rails. The 32 mm pattern notation signals that the hole layout follows the common 32 mm system, which helps line this slide up with cabinets drilled on that standard for faster layout and repeatable mounting.

How This 8500 Series Slide Works In Practice

Using The 28 Inch Slide In File Cabinets

The designation as a file drawer slide and the 28 inch length make this unit a practical choice where deep file drawers must open fully to expose folders. In a cabinet with the specified 1/2 inch plus 1/32 inch minus 0 inch side clearance per side, the slide positions the drawer so hanging file frames or file rails track evenly with the cabinet face. The full extension travel allows drawers to move completely out of the casework, giving users line-of-sight to labels at the rear. With the height of 3-51/64 inches including the quick disconnect rail, the slide occupies a defined band on the cabinet side, which helps designers stack multiple drawers vertically without interference between slide members. Because the product is made in USA and part of the KV Model 8500 series, shops that standardize on this line can keep replacement and expansion work consistent across multiple cabinets and installations over time.

Details That Support Smooth, Repeatable Operation

The ball bearing design with a retainer holding 3 bearings per inch of race spreads the load across multiple contact points, which helps the drawer glide smoothly even when a file drawer is heavily loaded. The hold-in feature that prevents bounce back keeps drawers seated against the face when pushed closed, which is important where rows of file cabinets must stay flush in corridors or office runs. Positive in and out stops define the endpoints of drawer travel, protecting the slide members from overextension during forceful pulls. Factory-attached drawer release clips with quick disconnect drawer members reduce time when drawers need to be removed for installing fronts, adjusting reveals, or servicing internal cabinet components. The recommended fasteners, #7 x 1/2 inch Phillips pan head, provide a specific screw type and length that match the slide design, which supports solid attachment into cabinet sides and drawer boxes without over-penetrating thin materials.
