    KV8850 28" Full Extension Soft-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 8850FMB 28

    Description

    Knape and Vogt 8850 Drawer Slides For Heavy Drawers

    Knape and Vogt 8850 drawer slides are 28 inch full extension, soft-close, ball bearing, side mount drawer slides that let drawers open their full length so the entire drawer depth is accessible during use. The 200 lb class rating supports heavy drawer loads, which suits storage where weight capacity and smooth travel are important. The soft-close module uses patented Force Management Technology to lower the opening pull force, so drawers start moving with less effort while still closing with controlled damping that prevents slamming. The unhanded side mount design installs on either side of the drawer, so one model covers both left and right applications. A lever release lets drawers be disconnected from the slides, which helps during cabinet installation and later removal for adjustment or service. The zinc finish provides a uniform plated surface that coordinates with typical cabinet hardware metals.

    Key Slide Details That Support Drawer Performance

    • The 28 inch length matches deeper drawer boxes, so the full extension design lets the drawer travel its entire length for clear access to stored items.
    • The 200 lb class slide rating supports heavy-duty loading, which matters in applications where drawers carry tools, hardware, or other dense materials on a regular basis.
    • The side mount, ball bearing construction provides guided movement along the cabinet sides, which helps drawers track straight under load and maintain consistent motion over time.
    • The soft-close module with Force Management Technology reduces opening effort and controls closing speed, which protects drawer fronts and cabinet faces from impact when drawers are pushed shut.
    • The unhanded design allows the same slide to be mounted on either side of the drawer, which simplifies specifying parts and using inventory across multiple cabinet runs.
    • The recommended #8 x 5/8 inch flathead screw fasteners match the mounting holes, supporting secure attachment into drawer and cabinet members for stable slide support.

    Installation Dimensions And Slide Mounting Details

    The recommended side clearance of 0.765 inch plus 0.03 inch minus 0 inch defines the gap between the drawer side and cabinet, which guides drawer box sizing so the slides fit without binding. The slide width of 0.76 inch occupies part of this clearance, shaping how the drawer and cabinet members share the available space. The 2.09 inch slide height determines how much vertical space the hardware needs on the drawer side, which influences drawer side height and placement relative to the cabinet opening. The side mount format positions the slide along the drawer sides and cabinet sides, which keeps the drawer bottom free and supports straightforward mounting in traditional cabinet layouts.

    Applying These 8850 Slides In Real Projects

    Where These 28 Inch Slides Are Typically Used

    The KV Model 8850 28 inch length is recommended for drawers up to 42 inches wide, which targets medium to very wide drawer fronts in base cabinets or storage pull-outs. The full extension travel suits drawers that need access to the entire contents, such as tool drawers, component storage, or workstation drawers where items at the back must be reachable. The 200 lb class rating supports use in heavy storage applications when paired with appropriate drawer construction, so users can load drawers with dense items while the slides guide movement along the cabinet sides. The lever release feature assists during installation in built-in cabinetry where drawers are often removed while casework is positioned and then reinstalled once alignment is set.

    How Slide Design Supports Consistent Drawer Results

    The soft-close module with Force Management Technology provides a low opening pull force, so drawers begin sliding without excessive effort even as loads increase, which helps maintain consistent user feel across a run of cabinets. The same mechanism dampens closing speed, so drawers decelerate before they seat, reducing stress on joinery and front alignment over time. The unhanded configuration allows installers to use one slide model on both sides of a drawer, which reduces part variation and supports consistent layout in production or multi-unit projects. The lever release design lets drawers be separated from the installed cabinet members, so installers can mount slides inside the case, test movement, and then reconnect drawers for final fit. The specific side clearance and slide dimensions provide defined targets for drawer sizing, which helps fabricators cut and assemble drawer boxes that work predictably with these slides.

    Common Questions About Knape And Vogt 8850 Slides

    What drawer size works with the 28 inch 8850 slides?

    The Knape and Vogt 8850FMB 28 slides are 28 inches long and are recommended for drawers up to 42 inches wide, which suits medium to wide drawer fronts in many cabinet layouts.

    How much side clearance do these slides require?

    The 8850FMB 28 slides use a recommended side clearance of 0.765 inch plus 0.03 inch minus 0 inch, which sets the gap between drawer side and cabinet for smooth slide operation.

    What is the load rating of the 8850FMB 28 slide?

    The 8850FMB 28 is a 200 lb class drawer slide, which supports heavy loads when combined with suitable drawer construction and mounting in demanding storage applications.

    How does the soft-close function work on these slides?

    Are these 8850 slides handed for left or right mounting?

    The Knape and Vogt 8850 series slides are non-handed, so the same 8850FMB 28 model mounts on either side of the drawer for simplified installation planning.

    What mounting screws are recommended for these slides?

    The 8850FMB 28 slides are recommended to be mounted with #8 x 5/8 inch flathead screws, which match the slide hole sizing for secure fastening into cabinet and drawer members.

    Selecting 8850FMB 28 Slides For Your Drawers

    The Knape and Vogt 8850FMB 28 soft-close side mount slide combines a 28 inch full extension length, 200 lb class rating, and unhanded design, which supports demanding drawer applications. The specified side clearance, 0.76 inch slide width, and 2.09 inch height give clear layout dimensions for building drawer boxes. The lever release and ball bearing construction assist during installation and later service. When a project calls for wide, heavy drawers with controlled soft closing, these 8850 series slides align with that requirement.
