KV8407 20" Full Extension Hold-in anti-rebound Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 8407B 20

Knape and Vogt 20 Inch Drawer Slides For Shelves

Knape and Vogt 20 inch drawer slides in the 8407 Series provide a full extension action, so a 20 inch shelf or drawer can travel its full length for clear access to stored items during cabinet or fixture use. The ball bearing design supports smooth movement along the slide, which helps maintain consistent operation when drawers are opened and closed repeatedly in woodworking or shop environments. A hold-in anti-rebound feature works to keep the drawer seated in the closed position, which matters when controlling drawer drift in cabinets. The 8407 model is described with shelf tabs, so the slide offers integrated shelf support points that simplify building pull-out shelves to a consistent reference. This side mount drawer slide is unhanded, which allows either side of the slide to be installed on the left or right, giving layout flexibility during installation and replacement work. The slide is made in the USA, aligning with projects that specify domestic hardware.

Key 8407B 20 Slide Details For Project Planning

• The 20 inch length supports medium-depth cabinet drawers, which suits many base cabinet and shelf pull-out designs that need full access to stored items.
• Side clearance of 1/2 inch plus 1/32 inch minus 0 each side defines the drawer-to-cabinet gap, helping set precise drawer box widths for smooth travel.
• The slide height of 1-13/16 inch establishes the vertical space required on the cabinet side, guiding rail placement and drawer side height decisions.
• A stated 32mm pattern is present, which aligns the slide with 32mm system drilling, allowing use with row-drilled cabinet sides common in production shops.
• The zinc finish provides a familiar metal surface on the slide members, supporting use in standard interior cabinetry where a plated slide is expected.
• Lever disconnect is listed as a feature, so the drawer member can be released from the cabinet member, which helps during installation, adjustments, and service.
• Shelf tabs are cited as a feature, which give builders defined bearing points for shelf-style pull-outs, simplifying repeatable shelf placement on multiple units.

Side Mount Fit, Clearance, And Fastener Selection

This 8407B 20 slide is a side mount design, so it attaches directly to the cabinet side, which suits face-frame or frameless layouts using lateral mounting. The side clearance of 1/2 inch plus 1/32 inch minus 0 each side gives a specific drawer box width relative to the opening, simplifying layout math when designing or retrofitting. With a height of 1-13/16 inch, the slide occupies a modest vertical band, leaving room for drawer construction details above and below the slide line. The recommended fasteners are #7 x 5/8 inch Phillips pan head screws, which indicate a screw length and head style that match the slide mounting holes and cabinet side thickness for dependable anchoring.

Using 8407B 20 Slides In Cabinet And Shelf Work

Where These 20 Inch Side Mount Slides Fit

The 20 inch full extension length supports base cabinets, utility cabinets, and shelf pull-outs that match this travel, which is common in kitchen, shop, or storage layouts. A side clearance of 1/2 inch plus 1/32 inch minus 0 each side defines the drawer box sizing window, so builders can cut sides and fronts to predictable dimensions and achieve a consistent slide fit across a run of cabinets. The 1-13/16 inch slide height keeps the hardware profile relatively compact, which benefits multi-drawer stacks where vertical spacing is tight and installers want hardware that shares a similar vertical band from one drawer to the next. The stated 32mm pattern aligns the slide with row-drilled cabinet sides, supporting efficient assembly in 32mm-based casework where hole spacing drives all hardware positions.

Details That Support Repeatable Drawer Performance

The ball bearing construction supports controlled, smooth movement along the full extension travel, which matters for drawers that are opened frequently and must track accurately without binding. The hold-in anti-rebound feature keeps the drawer seated in the closed position, reducing the chance of a partially open drawer interfering with traffic or other doors. Lever disconnect allows installers to separate the drawer member from the cabinet member, which speeds up fitting, simplifies handling of wider drawers, and aids removal for finishing or later adjustments. The unhanded side mount design means a single slide pattern can be used on both left and right sides, reducing sorting on the bench and simplifying replacement when swapping out existing 8407 Series hardware. The zinc finish provides a clean, plated surface that works well with typical interior cabinet conditions, supporting long-term use in woodworking projects supplied by Wurth Baer Supply.
