KV8908 20" Full Extension Hold-In/Hold-Out Ball Bearing Drawer Slides, Unhanded Side Mount Zinc - 8908B 20

Knape And Vogt 20 Inch Drawer Slides For Heavy Use

Knape and Vogt 20 inch drawer slides in the 8908 series provide a full extension ball bearing slide, so the drawer or pull-out can travel its full length for clear access to stored tools or supplies. The slide is a side mount drawer slide with a 3/4 inch side clearance, giving a defined gap that simplifies layout for cabinets, vehicle builds, or pantry pull-outs using standard carcass construction. A 3 inch height on the slide creates a tall, robust rail that supports heavy loads in demanding applications such as vehicles and large tool boxes. The non-handed design lets the same slide work on either side, which helps streamline ordering and setup on multi-drawer runs. A hold-in/hold-out function, described as lock-in and lock-out, stabilizes the slide at closed and extended positions, helpful when drawers operate under heavy load.

Heavy Duty Drawer Slide Details That Save Time

• The 8908 series full extension design allows the drawer to open its complete 20 inch length, improving reach to the back of the drawer during daily use in tool boxes or large pantry pull-outs.
• Ball bearing construction supports heavy-duty loads while allowing the slide to move without sticking, which is important when drawers carry dense tools, parts, or supplies and must still operate smoothly.
• The side clearance of 3/4 inch gives a clear dimensional target for cabinet and drawer sizing, reducing layout guesswork when building or retrofitting side mount drawers in vehicles or shop fixtures.
• The 3 inch slide height gives a substantial mounting surface on both cabinet member and drawer channel, aiding alignment and resistance to racking when drawers are loaded and cycled repeatedly.
• A non-handed design lets the same 8908B 20 slide work on left or right sides, simplifying inventory and helping installers set up pairs quickly without sorting handed components.
• The lock-in and lock-out mechanism that extends through the door front allows positive engagement under heavy load, which helps keep drawers either secured closed in motion or firmly extended while accessing contents.

Side Mount Slide Mounting And Fastener Setup

This Knape and Vogt side mount drawer slide uses a defined side clearance of 3/4 inch, so the installer can size the drawer box relative to the cabinet opening with that gap in mind for each side. The manufacturer specifies recommended fasteners as #10 (82 degree) flathead machine screws on the cabinet member, which lets the head sit flush for consistent clearance alongside the slide body. On the drawer channel, recommended fasteners are #10 panhead machine screws, providing a broad bearing surface against the drawer material to secure the moving member. Using the 3 inch slide height as a reference line, installers can position screws along the length of both members to resist twisting when the full extension travel is used. Together, the side clearance, slide height, and fastener guidance support accurate, repeatable side mount installations.

Using This 8908B 20 Slide In Real Projects

Where The 8908 Series Slide Works Best

The web description states that this slide is designed to be used in vehicles, tool boxes and large pantry pull-outs, which points directly to applications that see both heavy loads and frequent cycling. In vehicle builds, the lock-out function lets a pull-out stay extended under load while the lock-in function helps resist movement during transit, providing stability for stored equipment. Tool box drawers benefit from the heavy-duty ball bearings that carry the heaviest loads without sticking, giving smooth access even when drawers hold metal tools. Large pantry pull-outs gain from the full extension 20 inch travel, which brings stored items fully forward for visibility and reach. The 3 inch tall side mount profile suits robust cabinet constructions common in these applications, where stronger side rails are preferred.

Why These Slide Details Support Reliable Operation

The heavy-duty ball bearings are described as carrying the heaviest loads without sticking, so drawers loaded with tools or supplies can be operated repeatedly without binding, supporting efficient access during work. The lock-in and lock-out mechanism that extends through the door front allows the user to positively engage or release the slide from the working side, which is especially useful when drawers are deep or mounted in tight vehicle compartments. A non-handed design reduces setup complexity because one Knape and Vogt 20 inch drawer slides part number, 8908B 20, covers both sides of an opening, lowering the chance of installation errors related to left and right parts. The 3/4 inch side clearance gives a specific design dimension, which supports consistent drawer sizing across multiple cabinets or projects. The 3 inch height helps distribute forces along the rail, complementing the heavy-duty classification noted in the SAP description that labels this product as a heavy duty lock in/out unhanded rail.
