KV8900 48" Full Extension Standard Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 8900B 48
Description
Knape And Vogt 48 Inch Drawer Slides For Long Drawers
Knape and Vogt 48 inch drawer slides in the 8900 Series use full extension travel, so a 48 inch drawer opens its entire length for clear access to stored items along the full slide. The side mount design fits applications built around side-mounted hardware, keeping the drawer box supported along its length. A 3 inch height profile gives substantial vertical bearing area, which supports heavy drawers over the full stroke. The slides use standard ball bearing construction, so the drawer rides on rolling elements instead of sliding friction. That ball bearing design is specified for extra heavy-duty applications, allowing the slides to carry heavier loads than lighter duty runners. A zinc finish provides a metal surface that resists normal shop and jobsite handling. The non-handed design means the same member works on either side, so installers do not track left and right parts while mounting paired runners.
Key 8900B 48 Features That Support Demanding Use
- The full extension design lets the 48 inch drawer travel its complete length, giving access to the rear of the drawer without reaching over stored items.
- The side mount configuration supports drawer boxes on the cabinet sides, fitting casework designed around side-mounted ball bearing slides for predictable clearances.
- The side clearance of 3/4 inch sets a clear design target, so cabinet and drawer widths can be sized accurately around the hardware during layout and construction.
- The slide height of 3 inches provides a tall bearing profile, helping the ball bearing system support heavy loads over long extensions.
- The non-handed design uses identical parts for left and right, which simplifies installation steps and reduces sorting time during repetitive casework builds.
- The heavy duty ball bearings are specified for extra heavy-duty applications, so drawers built on these slides can be assigned substantial storage loads.
Mounting And Fastener Details For Accurate Fit
The Knape and Vogt 8900B 48 slide is a side mount design, so it installs along the drawer and cabinet sides rather than underneath the box. The specified side clearance of 3/4 inch defines the gap needed between drawer and cabinet, guiding box sizing to avoid binding. A slide height of 3 inches affects vertical placement on the drawer, helping installers align the hardware consistently from project to project. Recommended fasteners are #10 flat head machine screws on the cabinet member, giving a defined shank and head style for securing the slide into the case. The non-handed configuration means the same slide pattern mounts on either side, which keeps hole locations and clearances consistent when repeating installations.
Using 48 Inch KV 8900 Slides In Real Projects
Where These Extra Heavy Duty Slides Fit Best
The 48 inch length of the Knape and Vogt 8900B 48 slide suits deep drawers or pullout components where long travel is required, such as extended storage bays or full-depth casework. Full extension lets these deep drawers open completely, so contents at the far end can be reached without shifting front items. The side clearance of 3/4 inch helps designers and builders size wide, heavy drawers consistently in production work. With a 3 inch tall profile and heavy duty ball bearings, the slide aligns with extra heavy-duty applications where drawers may be assigned significant static loads. The side mount configuration works with cabinet designs that rely on strong side panels rather than bottom-mount supports, making these slides suitable for robust plywood or composite cases.
Details That Support Repeatable Sliding Performance
The Knape and Vogt 8900B 48 slide uses a non-handed pattern, so installers apply the same drilling and mounting layout on both sides of the cabinet, which supports repeatable alignment across multiple units. Full extension travel provides consistent stop positions at full open, helping projects that rely on predictable drawer exposure. The specified side clearance of 3/4 inch gives a numeric target for shop layouts, reducing trial-and-error fitting on long drawers. A 3 inch height gives more vertical surface for fasteners to grip, enhancing the joint between cabinet member and case side when using the recommended #10 flat head machine screw. Heavy duty ball bearings carry extra heavy-duty loads smoothly, helping the slides track reliably along their full 48 inch length.
