KV4450 18" Full Extension Soft-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 4450B 18

18 Inch Soft Close Drawer Slides For Smooth Access

18 inch soft close drawer slides in the Knape and Vogt 4450 Series provide full extension travel, so the drawer opens its full length and exposes the entire storage area for easy access during cabinet work. The soft-close function on these ball bearing slides controls the closing motion, which helps the drawer seat consistently in everyday use. An unhanded side mount design allows use on either side of the drawer, which simplifies layout and ordering in the shop. The low profile height of 1-13/32 inches keeps the slide compact, which helps when fitting hardware in tighter cabinet clearances. A maximum drawer width of 24 inches matches many standard cabinet layouts, so these slides fit common kitchen, bath, and shop drawer sizes. The zinc finish on these slides provides a uniform surface, which supports a clean, professional look inside the cabinet.

Key Drawer Slide Details That Support Your Builds

• The 18 inch length sets the drawer travel, which works well for many base and wall cabinets where full access to stored items is needed without over-travel.
• Full extension travel lets the drawer clear the face frame or front, which helps when loading tools, hardware, or supplies at the back of the box.
• Soft-close action on this 4450 Series slide manages the final closing distance, which helps drawers seat without slamming in day-to-day use.
• Side mount configuration positions the slide on the drawer sides, which suits traditional cabinet construction where the box sides are built to carry hardware.
• Ball bearing construction supports the moving members, which contributes to a consistent slide motion as the drawer opens and closes under normal loads.
• Unhanded design means each slide works on either left or right side, which simplifies stocking and reduces sorting time during installation.

Side Mount Fit, Clearances, And Fastener Pattern

This side mount slide uses a side clearance of 1/2 inch plus or minus 1/32 inch on each side, which sets a clear target for drawer box width when laying out cuts and joinery. A maximum drawer width of 24 inches aligns with many standard cabinet carcasses, which helps when repeating a proven drawer design across a run. The slide height of 1-13/32 inches keeps the hardware profile moderate, which is useful when side space must share room with drawer bottom details or other components. A 32 mm pattern is present, which supports cabinet construction that follows that drilling system. Recommended fasteners are #6 x 7/16 inch Phillips pan head screws, which ties the slide directly to a specific screw size and length.

How Knape And Vogt 4450B 18 Slides Work In Practice

Using These Slides In Cabinet And Drawer Runs

The Knape and Vogt 4450B 18 soft close slide is specified at 18 inches in length, which suits mid-depth drawers in kitchens, baths, and shop cabinetry where the carcass depth matches this size. A side clearance of 1/2 inch plus or minus 1/32 inch on each side defines the gap between the drawer and cabinet, which guides the exact drawer width during milling so the slide operates correctly. The maximum drawer width of 24 inches gives a clear upper width limit, which helps plan drawer fronts and internal storage without oversizing the box. Full extension travel means the moving members let the drawer come completely forward, which exposes stored parts, tools, or supplies without reaching around the front. The 1-13/32 inch slide height keeps the hardware close to the drawer bottom, which can be useful when working under lower side walls or near internal dividers. A zinc finish supports a consistent appearance across multiple drawers in a bank, which matters when building matching cabinet sets.

Details That Support Installation Speed And Consistency

The unhanded construction of this 4450 Series slide allows each member to serve either side, which streamlines installation because there is no left or right part to separate during staging. The side mount layout gives a predictable reference surface along the drawer side, which supports jigs or spacers that position the slide at the same height in each cabinet. Soft-close functionality in the slide controls the closing stroke, which helps drawers land in a repeatable position against the cabinet front in normal service. Ball bearing movement distributes load along the slide members, which contributes to a smoother action as drawers cycle during everyday opening and closing. The 32 mm pattern in the slide body lines up with systems using that drilling grid, which can reduce layout time when cabinets are produced with that standard. Recommended #6 x 7/16 inch Phillips pan head fasteners match the slide design, which helps the head and shank sit properly in the mounting holes and support long-term use.
