Knape And Vogt 20 Inch Over Travel Soft Close Drawer Slides

Knape and Vogt 20 inch over travel soft close drawer slides combine full extension, integrated soft-close, and side-mount ball bearing construction to support drawers that need smooth movement and controlled closing. These 8455 Series slides are rated at 90 pounds, so they handle typical cabinet drawers that carry tools, hardware, or supplies while maintaining consistent slide action under load. The full extension design allows the drawer to travel completely out of the cabinet opening, giving access to the full drawer length and simplifying work where clear reach to the back of the drawer is important. Integrated soft-close with Force Management technology slows the closing stroke, which reduces impact at the cabinet face and helps protect drawer fronts and face frames over repeated use. As a side mount drawer slide, this 8455FMP 20 model aligns along the cabinet side, supporting straightforward layout in common casework and shop-built cabinetry.

Key Working Details For 8455FMP 20 Installation

• The full extension 20 inch length provides access across the usable drawer depth, which supports storage layouts where items are placed toward the back without becoming hard to reach during daily use.
• The 90-pound rating defines the working load capacity, so drawers carrying tools, hardware bins, or dense materials can operate within a known weight range while maintaining ball bearing slide performance.
• The unhanded side mount design lets either member function on the left or right, simplifying layout and stocking because one slide configuration can serve both cabinet sides on a run of drawers.
• A side clearance of 1/2 inch plus 1/32 inch minus 0 inch per side sets a specific drawer box width target, helping builders size drawer boxes so the ball bearing members track cleanly without excessive play.
• The 1-13/16 inch slide height gives a defined profile to work around, which is useful when coordinating drawer side heights, clearances to cross members, and interference with internal cabinet features.
• The 32 mm pattern mounting option aligns hole positions with system construction, which speeds layout on line-bored cabinets and supports repeatable installation across multiple similar boxes.

Mounting And Drawer Fit For Side Mount Slides

This Knape and Vogt 8455FMP 20 model is a side mount, ball bearing drawer slide, so the cabinet and drawer members attach directly to the cabinet side and drawer side respectively. The specified side clearance of 1/2 inch plus 1/32 inch minus 0 inch per side gives a clear drawer-box-to-opening relationship that guides both shop fabrication and on-site fit adjustments. With a slide height of 1-13/16 inch, the hardware sets a predictable vertical footprint, which helps when coordinating drawer side heights and avoiding structural rails or shelf pins. Because the design is unhanded, one slide configuration works on either side of the drawer, simplifying layout in production runs. Full extension movement lets the drawer extend to its rated travel, aiding fit checks at the front so reveals and face alignment can be dialed in while maintaining the intended over-travel behavior.

Using 8455 Series Slides In Cabinet Builds

Where The 20 Inch 8455FMP 20 Slide Performs Best

The 20 inch length of the Knape and Vogt 8455FMP 20 slide matches common base and utility drawer depths, so it fits well in cabinets where standard carcass dimensions are used. Full extension operation lets the drawer move to the front of the slide travel, giving clear access to contents stored at the back, which is useful in shop cabinets, utility drawers, or storage banks where visibility matters. The 90-pound rating supports drawers holding heavier items such as fasteners, small tools, or dense supplies while maintaining ball bearing guidance. Three ball bearings per inch of slide length distribute load across multiple contact points, which supports smooth movement under working loads. Polymer stop cushions are integrated into the design, so end-of-travel contact is moderated, reducing impact when the drawer reaches its open position in day-to-day use.

The integrated soft-close with Force Management technology controls closing motion near the end of travel, pulling the drawer closed in a controlled way that reduces slamming and lessens stress on drawer fronts and cabinet frames. A push-in lever on the slide allows for easy drawer removal from the cabinet members, which is helpful during finishing, hardware installation, or later service work on interiors. Ball retainer latch and ramp features are built into the slide, easing drawer insertion onto the cabinet members so engagement can be completed without wrestling the hardware into alignment. The 32 mm pattern option works in cabinets built around system hole spacing, tying the slide layout into existing rows and supporting repeatable mounting across multiple cases without separate custom marking for each slide location.
