Knape and Vogt 8400 drawer slides use a ball bearing design that supports smooth full extension, so drawers travel fully out of the cabinet for clear access to stored items. The 20 inch length matches common cabinet depths where a standard-depth drawer is needed. A hold-in anti-rebound feature works with the ball bearings to resist drawers drifting back open after they are closed, which helps keep drawer fronts aligned in day-to-day use. These slides are unhanded side mount units, so each member can be used on either side of the drawer, which simplifies layout on the bench. The anochrome finish covers the slide members with a uniform metallic coating that is suited to typical shop and cabinet environments. As part of the Knape and Vogt 8400 Series, these slides carry a consistent platform of dimensions and features that supports repeatable installation across multiple cabinets.
The 20 inch Knape and Vogt 8400 side mount slide is designed for 1/2 inch side clearance plus 1/32 inch, minus 0 inch on each side, so case and drawer widths can be laid out to that specification for proper running fit. The slide height of 1-13/16 inch defines the vertical space the hardware occupies along the drawer side, which is important when stacking drawers or working around fixed interior elements. A 32 mm pattern is built into the slide, aligning with common system boring patterns used in cabinet construction, and that pattern helps coordinate hole locations between cabinet parts. The manufacturer recommends #7 x 1/2 inch Phillips truss head fasteners, which ties the slide design to a specific screw size and head style for seating against the mounting face.
The Knape and Vogt 20 inch full extension hold-in anti-rebound ball bearing drawer slides 8400 Series are side mount drawer slides suited to applications that call for a 20 inch slide length with 1/2 inch plus 1/32 inch side clearance on each side. The 1-13/16 inch height works with many face frame and frameless cabinet layouts where vertical space on the drawer side is limited but a robust slide section is required. Because these slides are non-handed, they fit installations where installers prefer to carry one part for either side rather than matched left and right pieces, which can simplify inventory in a shop. The 32 mm pattern supports cabinets built around system holes, so the slides tie into rows laid out on that standard. The anochrome finish supports interior use in woodworking and cabinetry where a neutral metal appearance is preferred. Being part of the 8400 Series links these slides with other lengths in the same family, supporting consistent planning across an entire project.
The full extension action of the 8400B 20 slide means the moving member travels the full 20 inch length, which lets the drawer box extend far enough for access to the complete storage area and for easier alignment of fronts. The ball retainer latch works with the ball bearing system to help keep the bearings positioned within the slide members, which supports lasting motion characteristics over repeated cycles. The hold-in anti-rebound element complements this by helping drawers stay shut after closing, which matters when faces need to stay flush in a row. Lever disconnect allows the drawer member to be separated from the cabinet member, which can streamline separate finishing of drawer boxes and cases or later adjustments. The recommended #7 x 1/2 inch Phillips truss head fasteners are matched to the mounting area on the slide, which supports proper head bearing on the steel. The specified 1/2 inch plus 1/32 inch minus 0 inch side clearance per side gives a clear target when sizing drawer boxes to cabinet openings so that both sides run evenly.
