Knape and Vogt 12 inch drawer slides in the 8400 Series give a 12 inch full extension, so the drawer travels its full length and exposes the entire contents for direct access during cabinet use or service work. The slide uses ball bearing construction, which supports smooth, consistent movement under load, helping drawers open and close cleanly in everyday shop and residential cabinet applications. A hold-in anti-rebound feature is part of this design, so the drawer is held in the closed position by the mechanism, which helps prevent the drawer from drifting back open after being pushed shut. These slides are unhanded side mount units, meaning the same model works on either side of the drawer, which simplifies layout, stocking, and installation on repetitive cabinet runs. The finish is white, matching white cabinet interiors or drawer boxes where a light, clean look is specified by the project.
The KV Model 8400 12 inch slide is specified with side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side, which defines the required gap between the drawer and cabinet for proper operation. This tolerance guides cabinet and drawer sizing, helping the installer cut components so the slide runs freely without excessive play. The slide height is 1-13/16 inches, so the drawer side must be tall enough to cover this height where the slide mounts. A 32 mm pattern is present, providing a regular hole spacing layout that aligns with 32 mm cabinet construction systems and jigs in many shops. Recommended fasteners are #7 x 1/2 inch Phillips truss head, which matches the slide holes and supports secure mounting into the cabinet and drawer members.
The KV Model 8400 12 inch side mount slides with white finish work well where a 12 inch drawer depth matches the cabinet interior, such as shorter base cabinets, utility cabinets, or upper cabinets with pull-out storage. The white finish gives a neutral, clean appearance inside painted or melamine-lined casework, which can be useful when the drawer sides or hardware are visible in open positions. Because the slides mount on the drawer sides, they pair with drawers built with straight, square sides that deliver the required side clearance of 1/2 inch plus 1/32 inch minus 0 inch per side. The 1-13/16 inch height also fits common drawer side heights used in system-based cabinet construction, so the slide can be placed within the structural part of the drawer side without conflict.
The hold-in anti-rebound feature on this 8400 Series slide helps drawers stay closed after being pushed shut, which is especially helpful on drawers mounted in higher-traffic areas where minor cabinet movement might otherwise nudge them open. Ball bearing operation supports smooth running over time, so drawers cycle reliably during everyday use. The lever disconnect is part of the slide design, allowing the drawer member to be separated from the cabinet member by operating the lever, which speeds up drawer removal during fitting, adjustment, or later service. A ball retainer latch is also specified, which helps keep the ball bearings correctly positioned within the slide members, supporting long-term movement quality. The 32 mm pattern lets installers use standard drilling equipment and line-boring layouts, tying the mounting directly into existing cabinet manufacturing processes for efficient production. The unhanded configuration further simplifies this process because the same component can be pulled for either side, keeping installation straightforward on repeated cabinet banks.
