KV4450 20" Full Extension Soft-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 4450B 20

Knape And Vogt 20 Inch Drawer Slides For Smooth Access

Knape and Vogt 20 inch drawer slides deliver full extension, so the drawer travels its full length and exposes the entire contents, which matters when installing cabinets that need clear access to the back for tools or stored materials. The slides use ball bearing construction, which supports smooth motion along the slide path and helps drawers open and close predictably under repeated use. A soft-close function is built into this 4450 Series slide, so the drawer is pulled gently closed at the end of travel, which helps reduce slamming impacts on the cabinet and drawer box. This model is a side mount drawer slide, so it installs along the drawer sides and cabinet case, which suits standard cabinet construction layouts. The slide is described as low profile, which keeps the slide height to 1-13/32 inches and leaves more vertical space for drawer box design in tight stacked layouts.

Key 4450B 20 Details That Support Daily Use

• The 4450B 20 slide length is 20 inches, which sets the drawer depth you can design into cabinet carcasses and lets you match slides to common 20 inch drawer box dimensions.
• This 4450 Series model provides full extension travel, so the drawer front pulls the box completely forward and exposes the full interior, which simplifies access and organizing in base and tall cabinets.
• A soft-close mechanism is integrated in the slide, which slows the final closing stroke and helps limit drawer bounce against the cabinet face, supporting quieter operation in shop or residential settings.
• The slide uses ball bearing construction, which provides guided steel-on-steel travel along the members and helps maintain alignment over many open-close cycles in service.
• This is an unhanded side mount slide, so either member can be applied to the left or right side, which simplifies layout and reduces orientation errors during installation runs.
• The zinc finish is specified, which provides a neutral metallic appearance and offers a treated surface that suits typical indoor cabinet environments.

Side Clearance, Height, And Mounting Pattern For Fit

The stated side clearance is 1/2 inch plus or minus 1/32 inch on each side, which defines the gap between the drawer and cabinet and guides the drawer box width you build for a consistent running fit. Slide height is listed as 1-13/32 inches, which sets the vertical space the slide occupies on the drawer side and helps when stacking multiple drawers in a cabinet opening. The 4450B 20 uses a 32 mm pattern, which lines up with standard system holes and speeds layout when cabinets are drilled on that system. The slide is a side mount model and uses #6 x 7/16 inch Phillips pan head fasteners as recommended, so you can match your screw schedule to the specified size for proper seating in the mounting slots.

Using The KV 4450B 20 Slides In Cabinet Builds

Where These 20 Inch Slides Fit Best

The 20 inch length on the KV Model 4450 20 suits cabinet designs where the interior depth supports a 20 inch drawer box, which is common in many base cabinet and shop storage layouts. With a maximum drawer width of 24 inches, this slide is specified for drawers up to that width, which helps when planning wider storage for tools, hardware, or kitchen items. The side clearance of 1/2 inch plus or minus 1/32 inch on each side defines the functional gap between the drawer and the case, so the drawer box can be sized to run smoothly without binding in the opening. Because the slide height is 1-13/32 inches, it works in banks of drawers where vertical space is controlled, helping you keep clearances tight without the members contacting adjacent drawers.

Details That Support Repeatable Drawer Results

The 32 mm pattern on the 4450B 20 matches standard system hole spacing, which supports repeatable mounting from cabinet to cabinet when you are using line-bored cases. The unhanded side mount design means the same slide can be applied to either side of the drawer, which streamlines assembly and limits sorting during installation. A soft-close feature in the slide automatically pulls the drawer fully closed at the end of travel, which helps keep drawer fronts aligned in a run and reduces adjustment work caused by partially closed drawers. The push button release feature allows the drawer member to be separated from the cabinet member, which simplifies drawer removal during finishing or service because the drawer can be detached without unfastening the slide from the cabinet. A hold-in detent feature keeps the drawer in the closed position at rest, which resists drift open and supports cleaner face alignment on installed cabinetry.
