8505B 30 drawer slide is a Knape and Vogt Model 8505 side mount ball bearing file drawer slide designed for applications needing a 30 inch length. This establishes a consistent travel range on deep file drawers where full access is critical. The slide is identified as a side mount drawer slide, so it supports lateral mounting to the cabinet sides on typical file drawer constructions. The product is part of the 8505 Series and is unhanded, which allows the same member design to be used on either side of the drawer during layout. Being a ball bearing file drawer slide, it uses bearing races to carry the load, giving smoother motion than friction runners in repeated daily use. The slide is described as over travel, which allows the drawer to extend past the cabinet face, improving reach to rear files in deeper drawers.
The 8505B 30 drawer slide is a side mount configuration, so it is intended to fasten to the cabinet side panels and the drawer sides in file drawer assemblies. Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the space between the drawer and cabinet, directly informing drawer box width for a free-running fit. The stated height of 3-51/64 inches including the quick disconnect rail sets a clear vertical envelope that interacts with drawer side heights and notching. A 32 mm pattern is provided, aligning mounting points with 32 mm system drilling for faster, more repeatable positioning in commercial casework layouts.
The Knape and Vogt 30 inch over travel hold-in anti-rebound ball bearing file drawer slide is oriented to file drawers requiring extended access. Being a file drawer slide, it suits cabinets designed to store file folders or similar content where full extension plus over travel is valuable. The over travel characteristic lets the drawer open beyond the cabinet front, improving reach to items at the back in deep drawers. Because the slide is unhanded, the same member design is used on both left and right sides, which streamlines planning and installation on banks of file drawers. As part of the 8505 Series and made in USA, it fits projects calling for this specific model designation, whether in new casework or matching existing installations built around the same series.
The 8505B 30 slide uses ball bearings with a retainer that holds 3 bearings per inch of race, which supports smooth and quiet motion in regular opening and closing cycles. Progressive movement on ball bearings means the sections of the slide extend in sequence along those bearings, contributing to consistent travel under load. Factory-attached drawer release clips with quick disconnect drawer members are specified, so drawer members can be separated from cabinet members through these clips, simplifying drawer removal and reinstallation when adjusting or servicing. A hold-in feature is described to prevent bounce back, helping the drawer stay in the closed position once pushed fully in. Positive in and out stops are listed, giving defined travel limits at both ends of the stroke, which helps protect the slide from over-travel beyond its designed range. Together these details translate into more predictable drawer action and alignment across multiple units.
The 8505B 30 slide is described as a ball bearing file drawer slide, so it is oriented toward file drawer applications where smooth extension and access to stored documents are required.
The 30 inch length with over travel allows the drawer to extend beyond the cabinet front, improving reach into the back of deeper file drawers built around that length.
The 8505B 30 drawer slide specifies side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side, guiding drawer box width relative to the cabinet opening.
The slide height is stated as 3-51/64 inches including the quick disconnect rail, which affects drawer side design and any required notching near the hardware.

The 8505B 30 slide has a hold-in feature to prevent bounce back, so when the drawer is fully closed it resists drifting open from minor movement.
The KV 8505 over travel slide in the 8505B 30 configuration combines a 30 inch length, defined 1/2 inch side clearance plus 1/32 inch minus 0 inch per side, and a 3-51/64 inch height to guide case and drawer sizing. Its over travel action, ball bearing construction with 3 bearings per inch of race, and progressive movement support smooth, quiet operation in file drawer applications. Factory-attached quick disconnect drawer members, hold-in feature, positive in and out stops, and a 32 mm pattern help streamline installation and ongoing use when building or updating file storage using this Knape and Vogt model.
