Knape and Vogt 30 inch drawer slides give a file drawer full extension travel so the drawer opens the complete length, which lets you access files or contents at the back without shifting heavy loads forward. These 8500 Series drawer slides are a side mount, ball bearing design, so the slide runs along the cabinet side and uses ball bearings for guided movement, which supports smooth and quiet drawer motion in daily use. The slide has a hold-in anti-rebound feature that resists drawer bounce back at the closed position, which helps the drawer stay shut instead of drifting open in a busy work area. The 8500 model is made in USA, which appeals to shops that standardize on domestic hardware for consistency across projects. These slides are part of the Knape and Vogt 8500 Series, so they match that series profile and performance for file drawer applications.
This KV 8500B 30 full extension slide is a side mount design, so the slide installs on the cabinet side wall and corresponding drawer side, which lines up with standard file drawer construction. Side clearance is 1/2 inch plus 1/32 inch minus 0 inch on each side, so the opening and drawer box are sized around that clearance, which supports predictable tracking without excessive play. The slide height of 3-51/64 inches including the quick disconnect rail gives a fixed profile, which helps determine where to position the slide on tall or shallow drawer sides. Recommended fasteners are #7 x 1/2 inch Phillips pan head screws (BST1/2X7-2C), so the mounting points are sized for that shank and head style, which provides a known anchor for securing the slide to wood cabinet sides and drawer material.
The 8500 Series is identified as file drawer slides, so the 30 inch length suits deeper file and storage drawers, which are common in office, commercial, and shop cabinetry. Being side mount drawer slides, they fasten to the cabinet and drawer sides, which aligns with typical box construction where the slide hardware bears the load along the vertical side panels. The full extension travel lets the drawer open completely, which put files or stored items fully in reach without compressing folders or shifting items just to reach the back. The model is made in USA, so it fits standard North American cabinet construction practices, which matters for shops that repeat the same drilling patterns and drawer proportions. The available Anochrome finish coordinates with a neutral metal appearance, which suits installations where hardware is occasionally visible when drawers are open.
The 8500B 30 slide uses a ball bearing design with a retainer that holds 3 bearings per inch of race, so each inch of slide travel rides on multiple bearings, which promotes smooth and quiet motion under drawer load. Factory-attached drawer release clips with quick disconnect drawer members are built into the slide, so the drawer can be separated from the cabinet member through those clips, which speeds removal and reinstallation during finishing, service, or layout adjustments. The slide has a hold-in feature to prevent bounce back, so at the closed position the mechanism resists the drawer rebounding, which keeps the front flush in normal operation. Positive in and out stops are part of the design, so travel is limited at both ends, which helps prevent the drawer from being pulled off the slide or slammed past its closed position during use. The 32 mm pattern support ties the mounting points to a known drilling system, which simplifies repeating hole locations on cabinet runs. The 30 inch side mount format within the 8500 Series lets a shop standardize across drawers of similar depth, which aids replacement, layout, and ordering under the same manufacturer part 8500B 30.
The 8500B 30 is a Knape and Vogt 30 inch side mount, ball bearing drawer slide, so it mounts to the sides and uses ball bearings to guide the drawer for smooth motion.
The slide is full extension, so the drawer travels the complete slide length, which exposes the back of the drawer for access in file and storage applications.
The slide is designed for 1/2 inch plus 1/32 inch minus 0 inch clearance on each side, which guides cabinet opening and drawer box sizing for proper fit.
The 8500B 30 slide height is 3-51/64 inches including the quick disconnect rail, which defines the vertical space the hardware occupies on the drawer side.
The 8500B 30 uses recommended #7 x 1/2 inch Phillips pan head screws, which match the mounting holes and provide a suitable anchor into cabinet and drawer material.
The 8500B 30 has hold-in anti-rebound, positive in and out stops, and factory-attached quick disconnect release clips, which support stable closing, limited travel, and straightforward drawer removal.
The 8500B 30 full extension slide pairs a 30 inch length with side mount, ball bearing construction, which suits deeper file drawers that need smooth travel to full open. The defined 1/2 inch plus 1/32 inch minus 0 inch side clearance and 3-51/64 inch height give clear layout dimensions, which supports consistent cabinet and drawer sizing across a project. Hold-in anti-rebound, positive stops, and factory-attached quick disconnect clips are built in, which streamline day-to-day use and drawer handling. For shops or serious DIY builders working with file drawer cabinetry that aligns with the 8500 Series profile, this Knape and Vogt 8500B 30 slide offers a defined specification to build around.
