KV8419 20" Over Travel Self-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Poly-Pack - 8419P 20

Knape And Vogt 20 Inch Over Travel Drawer Slides

Knape and Vogt 20 inch over travel drawer slides 8419P 20 are unhanded side mount ball bearing slides that support drawers needing smooth travel and self closing action. The side mount design positions the slides on the drawer sides, which suits standard cabinet construction where side panels carry the load and keeps the drawer bottom free for storage. The self closing feature pulls the drawer closed at the end of travel, which helps drawers settle in the same position and reduces partially open drawer fronts in busy shop or kitchen use. These slides provide 1 inch over travel, allowing the drawer to extend beyond full extension so the back of the drawer clears the face frame or cabinet front, which improves access to stored items at the rear. The zinc finish on these slides provides a clean, uniform appearance, which supports consistent hardware looks in production or retrofit projects.

Key Working Advantages Of KV 8419P 20 Slides

• The 1 inch over travel lets the drawer extend farther than its length, which exposes the rear of the drawer for easier loading and unloading in cabinets where access to the very back matters.
• The self closing feature pulls the drawer closed from the last part of travel, which helps align fronts consistently against the cabinet and reduces drawers left slightly open in everyday use.
• The unhanded design means the same 8419P 20 slide works on either side, which simplifies layout, reduces sorting during installation, and supports efficient assembly on site or in the shop.
• The lever disconnect allows the drawer member to separate from the cabinet member, which speeds up drawer removal for adjustments, finishing, or service work without disturbing cabinet mounting.
• The ball retainer latch keeps the ball bearings captured in the retainer, which supports smooth operation during repeated cycles and helps maintain slide action over the life of the drawer.
• Polymer stop cushions provide a cushioned stop at the end of travel, which softens closing impact against the slide and helps limit noise where drawers are frequently used.

Mounting And Fit Details For KV Side Mount Slides

The 8419P 20 side mount slide is specified for installations needing 1/2 inch plus or minus 1/32 inch side clearance on each side, which sets a precise gap between the drawer and cabinet for proper ball bearing engagement and smooth travel. The slide height is 1-13/16 inch, which lets installers coordinate drawer box heights and clearances when working with stacked drawers or existing cabinet openings. The 32 mm pattern is present on these slides, which aligns with common 32 mm system line boring and speeds up mounting in frameless or system-based cabinet construction. Knape and Vogt recommends #7 x 1/2 inch Phillips pan head fasteners for these slides, which matches the hole sizing in the slide members and supports secure attachment during production or retrofit work.

Using 8419P 20 Slides In Cabinet Projects

Where These 20 Inch Slides Fit Best

The 8419P 20 20 inch length suits drawer depths built around that nominal measurement, which fits common cabinet carcass depths used in many shop and residential layouts. Because the side clearance is specified at 1/2 inch plus or minus 1/32 inch on each side, these slides work in drawer boxes sized so the overall drawer width is cabinet opening width minus 1 inch, which helps installers hit a repeatable sizing formula. The zinc finish pairs cleanly with many cabinet interiors, which is useful where open slides may be visible in pullouts or utility cabinetry. The 32 mm pattern on the slide works well in cabinets drilled on that system spacing, letting mounting holes line up with existing rows so installers can place screws quickly along standard lines. With a height of 1-13/16 inch, these slides support use in medium-height drawers, leaving room above and below for clearances when planning vertical spacing in banks of drawers.

Details That Support Consistent Drawer Performance

The self closing feature on the 8419P 20 engages near the end of travel, drawing the drawer securely into the cabinet, which helps fronts sit flush and reduces the need to push drawers fully closed each time. The 1 inch over travel lets the drawer extend beyond full extension, which brings the rear of the drawer outside the face plane and improves visibility and reach to items stored at the back. The lever disconnect design lets the installer separate and reattach the drawer section of the slide without disturbing the cabinet section, which helps during finishing stages or when adjusting drawer fronts after installation. The ball retainer latch keeps the ball bearings held in the slide assembly, which preserves the running quality if the drawer member is removed and reinstalled multiple times. Polymer stop cushions at the end of travel soften the contact of moving parts, which supports smoother-feeling operation under repeated openings and closings in workspaces or residential settings.
