This is a 28 inch full-extension side-mount ball bearing drawer slide from Knape & Vogt's 8850 series, rated 200 lb per pair, with integrated Force Management soft-close damping and a zinc finish built for demanding indoor cabinet work.
A 200 lb rating per pair opens up applications that a standard 100 lb kitchen slide cannot safely cover. Floor-level pantry drawers loaded with canned goods, wide island drawers stocked with cookware, and heavy workshop or utility drawers all push past the standard class under realistic loads. At 28 inches, this slide suits deep cabinet runs where a shorter slide would leave the rear of the drawer inaccessible. Full extension means the whole drawer comes out to the face of the cabinet — nothing stays hidden at the back. The FM soft-close module works through the closing stroke regardless of how the drawer is pushed, so the close stays controlled even when the drawer is loaded to its limit.
Steel members carry a zinc finish that provides standard indoor corrosion protection for a side-mount slide that lives beside the drawer box, largely out of sight in service. Zinc is the working finish in this segment — durable and consistent across the steel members without adding visual weight to the cabinet interior. This SKU ships as a Bulk-Pack, the trade format for cabinet shops and contractors ordering in volume rather than retail polybags.
The 8850 series requires 3/4 inch of side clearance per side — notably more than the 1/2 inch that standard side-mount ball bearing slides need. Build the drawer box 1-1/2 inches narrower than the cabinet opening to leave the correct clearance on both sides. In face-frame cabinets, rear mounting brackets are required to support the back end of the slide; those brackets are series-specific and sold separately. Measure the cabinet's interior depth before ordering: the 28 inch slide length needs adequate clearance behind the closed drawer.
The 8850 series is engineered for 3/4 inch per side. Fitting it at 1/2 inch will bind the slide and prevent the drawer from operating correctly. Build the box 1-1/2 inches narrower than the opening, not 1 inch narrower.
200 lb is the rating per pair — both slides together. That is the number to compare against the weight your drawer will carry.
KV's FM system pairs a dampening cylinder with a balanced spring so the closing action adjusts to load — the drawer closes consistently whether it is empty or full. It is a damped close, not an undamped self-close spring.
No. The 8850 series is non-handed — the same slide fits either side. Order the number of pairs your drawer count requires.
Face-frame cabinets need rear mounting brackets to support the back end of the slide. The brackets are series-specific and sold separately — confirm the correct bracket for the 8850 series before ordering.
The KV 8850 FM in zinc is the heavy-load, soft-close answer for the drawers in a cabinet run that standard slides are not rated for — pantry pull-outs, wide island drawers, and deep utility cabinets where 200 lb capacity and quiet, controlled closing both matter.
