KV8850 14" Full Extension Soft-Close Ball Bearing Drawer Slides, Unhanded Side Mount Zinc Bulk-Pack - 8850FMB 14

Knape And Vogt 14 Inch Soft Close Drawer Slides

Knape and Vogt 14 inch soft close drawer slides are full extension, ball bearing, side mount slides designed for drawers handling heavy loads. The 200 lb class rating supports demanding drawer applications, so wide or heavily loaded drawers stay functional under weight. The full extension design lets the drawer travel its entire length, which exposes the full drawer interior for easier access to stored items. The soft-close module uses patented Force Management Technology to deliver low opening pull force while still providing effective dampening closure, so drawers open with less effort yet close in a controlled way that eliminates drawer slamming in daily use. The non-handed design allows installation on either side without handed parts, which simplifies layout on site and reduces part sorting. The unhanded configuration also helps when installing multiple drawers in production runs where consistency matters.

Key Drawer Slide Details That Support Heavy Use

• The 200 lb class drawer slide rating supports heavy loads, so drawers carrying tools, hardware, or dense materials operate within the slide's design capacity in workshop, shop-fit, or cabinetry environments where weight adds up.
• The full extension slide travel brings the drawer fully out of the cabinet, which improves reach to the back of the drawer and reduces time spent searching or unloading items just to access rear contents during regular work.
• The soft-close module with patented Force Management Technology delivers low opening pull force and effective dampening, so users experience an easier initial pull while the drawer still closes smoothly without impact, helping reduce wear on drawer fronts.
• The non-handed design allows mounting on either side of the drawer, which streamlines inventory for installers and supports faster installation by eliminating left and right part tracking in the shop or on the jobsite.
• The lever release feature allows the drawer to be disconnected from the slide, which supports drawer removal for cabinet servicing, finishing, or adjustments and then reattachment without dismantling the entire installation.
• The zinc finish identified in the description provides a metal surface treatment, which supports a consistent slide appearance that matches common cabinet hardware finishes in many shop-built and commercial installations.

Side Mount Fit, Clearances, And Fastener Details

This Knape and Vogt 8850 series slide is a side mount, ball bearing design, so it installs along the drawer sides rather than under the drawer box. The recommended side clearance is 0.765 inches plus 0.03 inches minus 0 inches, which defines the required space between drawer side and cabinet side for proper action. Working to that clearance range helps the ball bearings run smoothly under load. The slide width is 0.76 inches, so the slide occupies a consistent footprint along the drawer side when planning cabinet interior dimensions. A slide height of 2.09 inches defines how much vertical space the slide uses on the drawer side panel. Recommended fasteners are #8 x 5/8 inch flathead screws, so mounting holes are designed to work with that screw size during installation.

Using 8850FMB 14 Slides In Cabinet Projects

Where These 8850 Series Drawer Slides Fit Best

The KV Model 8850 in 14 inch length is recommended for drawers up to 42 inches wide, so it supports wide drawer designs in cabinets, shop storage, and similar applications. That recommendation provides guidance when planning drawer width so the 200 lb class rating and slide geometry work together on larger fronts. The side mount style suits cabinet constructions that use traditional side-mounted slides rather than undermount hardware, which is common in many shop-built and commercial casework systems. Because the slide is ideal for wide drawers with heavy loads, it works well in tool drawers, hardware storage, and deeper base cabinets where contents are dense. The ball bearing mechanism provides guided motion under load, which supports consistent opening and closing even when the drawer weight is concentrated toward the front.

Details That Support Repeatable Drawer Performance

The 8850FMB 14 part number identifies a specific 14 inch length within the 8850 series, which helps match slide length accurately to drawer depth during layout or replacements. The 0.765 inch side clearance and 0.76 inch slide width together establish a predictable interface between drawer box and cabinet, supporting repeatable fit across multiple cabinets. The soft-close module's Force Management Technology keeps opening pull force low while ensuring dampening closure, so users experience predictable movement from drawer to drawer in a bank. The lever release simplifies removing drawers to adjust clearances or align faces, which supports fine-tuning reveals without disassembling slide hardware from the cabinet. The 2.09 inch slide height offers a known profile along the drawer side, helping designers position drawer bottoms and side heights so slide placement remains consistent across a project.
