Knape and Vogt 18 inch drawer slides give a file drawer full extension travel, so the 18 inch length lets the drawer open its full depth for clear access to files and contents during work. The 8500 Series side mount design sets the slides on the cabinet sides, which suits typical file drawer construction and keeps the bottom open for folders or hanging file frames. A hold-in anti-rebound feature keeps the drawer pulled closed at the end of travel, which helps the drawer stay shut instead of drifting back out after closing. Ball bearing construction with a retainer that holds 3 bearings per inch of race supports smooth and quiet motion, so drawers move cleanly even under load. An unhanded configuration means the same slide model works on either side, simplifying layout and stocking for multiple drawers.
The 18 inch KV Model 8500 uses side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side, so cabinet and drawer widths can be laid out to that running clearance for a consistent fit. A height of 3-51/64 inch, including the quick disconnect rail, defines the vertical space needed along the drawer side, helping with drawer box height decisions and clearance to rails or openings. The 32 mm pattern on the slide lines up with 32 mm system drilling, so cabinets built on that system can place mounting holes quickly without custom layouts. Recommended fasteners are #7 x 1/2 inch Phillips pan head screws, so installers can match the slide hole sizing and head style for solid mounting. The available Anochrome finish gives the steel slide a uniform appearance, which helps match other hardware in similar finishes.
KV Model 8500 file drawer slides are part of a side mount drawer slide class, so they fit typical side-mounted file and storage drawers where the slide runs along each drawer side. The made in USA designation ties directly to Knape and Vogt production, which matters to shops standardizing on a domestic source for repeat projects. As side mount, ball bearing slides for file drawer use, they fit cabinets that need full extension to expose file contents while keeping the drawer supported along its travel path. The Anochrome finish provides a clean, neutral tone on the visible slide edges, which suits office, commercial, or shop casework using light or neutral interior finishes. Because these are unhanded side members, left and right positions use the same part number, which simplifies ordering for banks of identical file drawers.
The 1/2 inch plus 1/32 inch minus 0 inch side clearance per side sets a specific gap between the drawer and cabinet, which supports predictable slide engagement and reduces trial-and-error fitting. The 3-51/64 inch slide height means installers can plan drawer heights with known space taken by the slide, avoiding interference with horizontal dividers or face frame openings. Factory-attached drawer release clips with quick disconnect drawer members allow the drawer to be mounted, test-fit, and then removed for front work or adjustments without disturbing cabinet members. The positive in and out stops control travel limits at both ends, which keeps drawers from pulling past the slide length or slamming deeper than designed. A retainer holding 3 bearings per inch of race maintains bearing distribution along the slide, which keeps motion smooth under repeated cycles and helps maintain alignment during long-term use in filing applications.
KV 8500B 18 slides are side mount, ball bearing file drawer slides, so they suit file and storage drawers that need full extension access along the drawer side panels.
The 8500B 18 slides use 1/2 inch plus 1/32 inch minus 0 inch side clearance per side, so drawer and cabinet widths can be planned to that gap for smooth slide operation.
The hold-in anti-rebound feature keeps the drawer held at the closed position, which helps prevent the drawer from drifting or bouncing back open after closing.
The factory-attached drawer release clips with quick disconnect drawer members let the drawer be removed from the cabinet members, which simplifies mounting, adjustments, and service work.
The 8500B 18 slides are recommended for use with #7 x 1/2 inch Phillips pan head screws, so fastener sizing and head style match the slide hole design.
The KV 8500B 18 slide height is 3-51/64 inch including the quick disconnect rail, so cabinet and drawer designs can allocate vertical space around that dimension.
The KV 8500B 18 full extension file drawer slide ties together 18 inch travel, side mount configuration, and a hold-in anti-rebound feature, so file drawers open fully yet stay shut when closed.

For projects calling for made in USA side mount, ball bearing file drawer slides, this 8500B 18 model provides a consistent Knape and Vogt option.
