KV8908 40" Full Extension Hold-In/Hold-Out Ball Bearing Drawer Slides, Unhanded Side Mount Zinc - 8908B 40

Knape And Vogt 40 Inch Drawer Slides For Heavy Use

Knape and Vogt 40 inch drawer slides give you a full extension ball bearing slide for long, heavy drawers that need to open their entire length. The 8908B 40 model is a side mount drawer slide, so it runs on the cabinet sidewalls where most installers expect to work. A non-handed design lets the same slide work on either side, which simplifies layout and reduces part variation on the job. The slide is designed to be used in vehicles, tool boxes and large pantry pull-outs, so it suits mobile and stationary storage where drawers carry substantial weight. A lock-out mechanism holds the slide open under load, keeping drawers from rolling back while tools or supplies are accessed. A lock-in mechanism holds the slide closed, which is important in vehicles or tall pantry pull-outs where movement or tipping forces can shift drawers unexpectedly.

Heavy Duty Slide Details That Support Demanding Jobs

• The 40 inch length allows deep drawers to extend fully, so contents at the back of vehicle, tool box or pantry pull-outs stay reachable without overreaching into the cabinet.
• The full extension ball bearing design carries the heaviest loads without sticking, which keeps long drawers moving smoothly even when packed with tools or supplies.
• The side mount configuration matches standard cabinet construction, so the slide works with typical side panels instead of requiring alternate mounting structures.
• The 3 inch slide height provides a substantial bearing profile, which supports heavy-duty use on tall or deep drawers that see frequent operation.
• The 3/4 inch side clearance defines the space between drawer and cabinet, guiding builders to size drawer boxes correctly for a consistent fit.
• The non-handed design means a single part number serves left and right sides, helping shops simplify inventory and reduce setup errors during installation.

Side Mount Installation And Screw Selection Details

This 8908 Series slide is a side mount design, so it fastens to the cabinet member on each side and to a matching drawer channel. Recommended fasteners are #10 (82 degree) flathead machine screws on the cabinet member, providing a flush mount where the slide face needs to sit tight to the panel. On the drawer channel, recommended fasteners are #10 panhead machine screws, giving positive bearing against the channel surface. The specified fasteners create a secure connection that supports heavy loads while keeping the slide aligned along its full 40 inch travel. With side clearance set at 3/4 inch and slide height of 3 inches, installers can dimension drawer boxes and cabinet openings to match these measurements.

Why This 8908B 40 Slide Fits Demanding Storage

Using The 8908B 40 In Vehicles, Tool Boxes, Pantries

The 8908B 40 slide is designed to be used in vehicles, which means the lock-in mechanism keeps drawers closed when a vehicle moves or vibrates, helping heavy contents stay contained. On large tool boxes, the full extension ball bearing action lets drawers pull all the way out, so tools at the very back remain accessible while the heavy-duty bearings carry the heaviest loads without sticking. In large pantry pull-outs, the 40 inch length supports tall, deep pantry frames that travel fully out of the cabinet face, letting stored items travel into clear view. The lock-out mechanism is especially useful on tall pantry pull-outs or vehicle-mounted drawers, holding the slide open during access so the assembly does not slide back under load. The side mount configuration works naturally with common cabinetry and storage frames, which helps standardize drawer construction across shop, truck, and kitchen applications.

Details That Support Alignment, Load, And Repeatable Results

The slide height of 3 inches provides a larger bearing track than many lighter-duty slides, which helps stabilize long drawers over the entire 40 inch travel. Side clearance of 3/4 inch defines the required gap on each side, so drawer widths can be sized to prevent binding while still controlling side-to-side movement. Non-handed design simplifies installation, because the same 8908B 40 part serves both left and right sides, reducing the chance of installing a wrong-hand slide during assembly or service. The lock-in feature extends through the door front, giving a direct control point on the slide for holding the drawer closed under heavy load. The lock-out feature also extends through the door front, providing a positive open position that keeps drawers from drifting when loaded. Heavy-duty ball bearings are rated to carry the heaviest loads without sticking, which supports reliable performance when drawers are filled with tools, parts, or pantry goods.
