KV8455 18" Over Travel Soft-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Poly-Pack - 8455FMP 18

Knape And Vogt 18 Inch Soft Close Over Travel Slides

Knape and Vogt 18 inch over travel soft close drawer slides give full extension, so the 18 inch length lets the drawer open completely for direct access to the contents, which simplifies loading and unloading in cabinet builds. This 8455 Series, side mount, ball bearing design keeps the slide running on a defined path, supporting predictable drawer motion along the cabinet side. The 90 pound rated load capacity means the slide is built to carry typical residential and many light commercial drawer loads without deforming under normal use. Integrated soft-close with Force Management technology controls closing speed at the end of travel, so drawers close gently instead of slamming, reducing impact on cabinet fronts over time. The over travel action moves the drawer slightly past full extension, bringing the back of the drawer clear of the face frame, which improves reach to stored items and hardware at the rear.

Key Slide Details That Support Cabinet Work

• The full extension 90 pound rated integrated soft-close design combines reach and load support, so drawers can be built deep and still run smoothly under everyday weight.
• Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the drawer box width, guiding installers to size boxes accurately for consistent fit across a run.
• The 1-13/16 inch slide height matches common cabinet layouts, helping drawers stack vertically while staying within standard cabinet side dimensions.
• The 18 inch nominal length suits many base and utility cabinet depths, simplifying planning when standardizing drawer sizes in a project.
• Three ball bearings per inch and polymer stop cushions support smooth, quiet operation, which reduces vibration on joinery and contents during everyday use.
• The non-handed side mount design lets either slide work on either cabinet side, which streamlines layout and reduces orientation checks during installation.

Mounting, Clearance, And Drawer Removal Details

This 8455FMP 18 side mount drawer slide uses a 32 mm pattern, so hole positions align with that system on cabinet sides for repeatable mounting across multiple boxes. Side clearance of 1/2 inch plus 1/32 inch minus 0 inch per side sets a precise gap, so a drawer built to that width will ride properly on the ball bearings without binding. The 1-13/16 inch height fits standard cabinet side spaces, allowing slides to be stacked vertically without crowding the opening. A push-in lever allows easy drawer removal from the slide, which speeds finishing, adjustments, and service work because drawers can be lifted out without tools when needed.

Where These 8455 Series Slides Work Best

The Knape and Vogt 18 inch over travel soft close drawer slides sit in the Side Mount Drawer Slides class, so they mount directly to the cabinet sides, making them a match for face frame or frameless layouts that accept side-mounted hardware. Their 18 inch length fits many kitchen, bath, and shop cabinets built around common depths, so a single model can often serve multiple drawer positions in a run. The 90 pound rated capacity covers typical utensil, office, or light tool drawers, so the same slide can support a broad range of storage without changing models between locations. Because the design is non-handed, each member of the pair can mount on either the left or right cabinet side, which is useful when working quickly or when slides are stored in bulk and pulled directly to the bench. The 32 mm pattern ties into system drilling, allowing rows of cabinets to share identical hole layouts for the slides.

Details That Support Repeatable Slide Installation

These 8455FMP 18 drawer slides use three ball bearings per inch, which distributes the load across multiple contact points, helping the drawer travel feel consistent from closed to over travel without catching. Polymer stop cushions work with the ball bearings to soften contact at the ends of travel, which reduces noise and limits shock on drawer joints when reaching full extension. The integrated soft-close with Force Management technology takes over near closing, managing the final portion of travel so the drawer front draws in steadily against the cabinet without rebounding, which helps maintain alignment of reveals along a bank of drawers. A ball retainer latch and ramps allow for easy drawer insertion onto the slides, so the drawer can be engaged firmly into the ball bearing carrier without complex manipulation, supporting quick, repeatable assembly on site or in the shop. The specified side clearance of 1/2 inch plus 1/32 inch minus 0 inch each side ties directly into drawer box sizing, so once the first box is dialed in, subsequent boxes can be cut to the same width for a consistent fit on every slide in the project.
