8450FMP 20 Drawer Slides For Smooth Soft Closing

8450FMP 20 drawer slides are Knape and Vogt 20 inch full extension side mount drawer slides with an integrated soft-close feature, so drawers travel their full length and then close gently for controlled movement in everyday use. The slides are rated at 100 pounds, which supports typical drawer loads where a medium-duty slide is needed in cabinets and casework. An unhanded, non-handed design allows the same slide to be used on either side of the drawer, simplifying layout and reducing part sorting during installation. These slides use ball bearing construction, giving consistent, guided motion along the case member. A zinc finish provides a clean, uniform surface that works well in shop environments where metal hardware is exposed during installation and adjustment.

Key Drawer Slide Details That Support Daily Use

• Full extension travel lets the 20 inch drawer open its full length, giving access to the back of the drawer without reaching around the cabinet front.
• The integrated soft-close with Force Management technology controls closing speed, which helps drawers settle without slamming against the cabinet front.
• A 100 pound load rating supports drawers built for typical storage tasks, helping the slide handle weight across its full extension.
• Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side gives a specific target for drawer box sizing relative to the cabinet opening.
• The 1-13/16 inch slide height defines how much vertical space the hardware occupies, which helps when stacking drawers or working near fixed shelves.
• The 32 mm pattern allows mounting within systems laid out on 32 mm increments, supporting consistent hole spacing on cabinet sides.
• Three ball bearings per inch and polymer stop cushions create smooth, quiet operation, which is useful in occupied spaces where noise matters.
• The push-in lever enables easy drawer removal, which helps during finishing, adjustments, or later service work on the drawer box.
• The ball retainer latch and ramps aid easy drawer insertion, guiding the members together when mounting the drawer into the cabinet member.
• Recommended fasteners of #7 x 5/8 inch Phillips pan head screws give a defined screw size that matches the slide holes during installation.

Installation And Side Mount Fit Details

These Knape and Vogt 8450 series side mount ball bearing slides are designed for side mounting, so the 1/2 inch plus 1/32 inch minus 0 inch side clearance per side directly informs drawer box width within the cabinet opening. The 1-13/16 inch height of the slide helps determine vertical layout when placing multiple drawers in a stack, especially in frameless cabinets using a 32 mm pattern. The non-handed design means the same slide can be installed on either side without orientation concerns, which can speed installation in repetitive cabinet runs. The recommended #7 x 5/8 inch Phillips pan head screws match the slide mounting holes, supporting consistent holding power along the length of the cabinet and drawer members.

Where These Full Extension Slides Work Best

20 Inch Side Mount Slides In Cabinet Projects

The Knape and Vogt 8450 series 20 inch full extension 100 pound rated slides fit projects where a drawer needs full travel to expose the complete box, such as base cabinets, utility drawers, and similar casework. Their side mount design suits cabinets built for traditional slide positioning along the cabinet sides, matching many existing shop construction methods. With side clearance of 1/2 inch plus 1/32 inch minus 0 inch each side, these slides support drawer boxes sized for precise fit within evenly built openings. The 32 mm pattern aligns with cabinet systems drilled on that spacing, which is common in frameless construction and line-bored interiors. Ball bearing construction with three ball bearings per inch supports smooth guidance as the drawer moves in and out under load. Polymer stop cushions work with the soft-close function to reduce impact at full closure, useful in residential and commercial interiors.

Design Details That Support Repeatable Results

The integrated soft-close with Force Management technology manages closing force as the drawer nears the cabinet, helping installers deliver drawers that feel controlled without separate closing devices. The 100 pound load rating sets a defined performance range, giving confidence when matching drawer contents to slide capability. A non-handed design keeps left and right installations identical, simplifying inventory and reducing orientation errors on the bench. The push-in lever for easy drawer removal allows the drawer box to be taken out after installation, which helps during site finishing, hardware adjustment, or access to utilities behind the cabinet. Ball retainer latch and ramps assist with easy drawer insertion by drawing the members together as the drawer is pushed in, which supports faster assembly, especially when working alone. The 1-13/16 inch height provides a predictable profile that fits consistently under drawer sides, allowing repeatable jig setups and clearances across a run of drawers.
