Knape and Vogt 28 inch over travel drawer slide uses the KV Model 8505 in a side mount, ball bearing design, so file drawers open past the cabinet front for better access. The 28 inch length supports full-depth file drawers where extra extension is useful. An over travel action lets the drawer clear the cabinet face, which helps when folders or contents sit high in the drawer. The unhanded side mount layout means the same slide works on either side of the drawer, simplifying layout on a bank of file drawers. Ball bearing construction creates progressive movement along the race, so the drawer motion stays smooth from initial pull to full extension. The hold-in anti-rebound feature keeps the drawer seated when closed, which matters on rolling cabinets or in busy office environments. Positive in and out stops define the travel limits, helping protect both the slide and the cabinet structure.
This 28 inch side mount drawer slide uses a 1/2 inch plus 1/32 inch minus 0 inch side clearance on each side, which guides drawer box width when planning casework. That fixed clearance also helps when retrofitting drawers into existing cabinet openings that already follow similar gaps. The unhanded configuration means each member can be used on either side, which can reduce sorting on site. Height of 3-51/64 inch including the quick disconnect rail defines the vertical envelope, which matters around drawer bottoms, runners, and face frame openings. The recommended fasteners are #7 x 5/8 inch Phillips pan head screws, so the mounting pattern matches a common screw size found in shop stock. Quick disconnect drawer members work with factory-attached drawer release clips, which allows drawers to be removed for installation, finishing, or service and then reinstalled on the same members.
The Knape and Vogt Model 8505B 28 inch slide is identified as a file drawer slide, so it suits lateral or deep file storage where full access to hanging folders is important. Over travel movement pushes the drawer out past the cabinet front, which keeps folder tabs easier to read when the cabinet face projects beyond the internal box. Side mount orientation follows standard cabinet construction, so designers can pair this slide with common drawer box designs using a 1/2 inch plus 1/32 inch minus 0 inch clearance on each side. The unhanded layout helps when installing multiple drawers across several cabinets because any slide can serve either side of a given drawer. Support for a 32 mm pattern makes this slide a practical match for frameless cabinetry that already uses line boring at that spacing in the gables.
The KV 8505 slide uses progressive movement on ball bearings, which spreads load over multiple bearing sets as the drawer moves, supporting smoother travel across the full extension. A retainer that holds 3 bearings per inch of race further stabilizes the movement, which can reduce play in the drawer as it opens and closes. Positive in and out stops define end points in both directions, which protects the race from over-extension and keeps the drawer from pushing into the cabinet. Factory-attached drawer release clips connect to a quick disconnect drawer member, which lets installers hang the cabinet members first, then drop drawers on in sequence for a consistent fit. The Anochrome finish identifies the surface treatment, which pairs visually with other Anochrome-finished slides in the same installation. Identifying the product as KV Model 8505, made in USA, ties it directly to Knape and Vogt reference drawings and job schedules using that series number.
The KV 8505B 28 is a 28 inch Knape and Vogt side mount ball bearing file drawer slide, so it supports full-depth file drawers that need smooth movement and defined over travel.
The slide uses 1/2 inch plus 1/32 inch minus 0 inch side clearance on each side, which sets the drawer box width needed for a proper fit in the cabinet opening.
The 8505 series in this version has a height of 3-51/64 inch including the quick disconnect rail, which defines the minimum vertical space between drawer and cabinet members.
The hold in anti rebound design keeps the drawer pulled firmly closed, which helps prevent file drawers from drifting open when cabinets experience vibration or frequent movement.
This Knape and Vogt slide supports a 32 mm pattern, which works well in frameless cabinets or casework laid out using 32 mm system line boring in the gables.
The recommended fasteners are #7 x 5/8 inch Phillips pan head screws, so installers can align slide mounting with a standard screw size used in many cabinet shops.
The Knape and Vogt 28 inch over travel drawer slide with 1/2 inch plus 1/32 inch minus 0 inch side clearance provides a defined fit for file drawers where reaching the back of the drawer matters. The side mount, unhanded design and 3-51/64 inch height make it straightforward to integrate into new or existing casework. Quick disconnect drawer members with factory-attached release clips support efficient installation and later adjustments. When a job calls for a 28 inch KV Model 8505, made in USA, side mount ball bearing file drawer slide, this 8505B 28 configuration aligns directly with that specification.
