20 inch full extension drawer slide describes this Knape and Vogt 6500B 20 side mount, ball bearing file drawer slide that supports full access to the drawer opening, which helps installers build file drawers that open completely for easier use. The slide is a standard ball bearing design, so the moving members travel smoothly on bearings, which supports repeatable action over many open-and-close cycles. This model is part of the KV 6500 Series, so it matches that series geometry for projects built around that line. The slide is unhanded, so the same member works on either the left or right side, which simplifies ordering and layout. It is a side mount drawer slide, so it fits along the drawer sides, which suits common cabinetry construction where side panels carry the load and keep the drawer guided.
The 6500B 20 is a side mount ball bearing slide, so it installs along the drawer sides and cabinet interior, which matches standard construction for file drawers and lets installers work with familiar screw positions. The slide provides full extension, so the drawer travels its full length out of the cabinet, which helps with access to file folders or stored items at the back of the drawer. A lever disconnect rail feature is specified, so the drawer member can be released with a lever, which simplifies separating the drawer from the cabinet member during installation or later servicing. A closed position hold-in detent is also noted, so the slide resists creep-out from the closed position, which helps drawers stay shut when cabinets are bumped or when fronts are slightly out of level.
This Knape and Vogt 6500B 20 file drawer slide is identified specifically as a file drawer slide, so it is aimed at applications where drawers carry documents or similar stored items in cabinetry. The heavy duty description ties directly to those file drawer loads, which often concentrate weight toward the front as users access files, so the slide design supports those conditions. Its 20 inch length suits cabinets and pedestals built for standard-depth drawers, so it works well in office, shop, or storage furniture designed around that dimension. Because the slide is side mount, it fits into casework with solid sides, which is common for file and storage units where fixing to the side panels keeps drawers aligned. The zinc finish keeps the appearance neutral inside cabinets, which helps projects where visible hardware should blend with typical metal drawer components.
The specified side clearance of 1/2 inch plus 1/32 minus 0 inch per side gives a tight tolerance window, which helps cabinetmakers dimension drawer widths to achieve smooth running without rattle or bind. The slide height of 2-19/32 inch informs the minimum drawer side height and opening allowance, which supports accurate layout when multiple drawers stack in a cabinet. The presence of a 32mm pattern aligns screw locations with 32mm system holes, which allows production shops using line boring to position slides quickly and consistently. The lever disconnect rail feature allows installers to remove the drawer member after initial mounting, which simplifies adjustments to cabinet members or drawer faces without wrestling a full assembly. The closed position hold-in detent supports cleaner reveals on file drawer faces, because drawers tend to stay aligned in the closed position even after repeated use.
