The Knape and Vogt 8400 Series 12 inch side-mount ball bearing drawer slide in Ebony Black is a full-extension, 100 lb rated pair built for cabinetry where a dark finish matters — dark-interior frameless boxes, blackened shop cabinets, or modern handleless kitchens where exposed hardware should disappear rather than contrast. Sold as a Bulk-Pack for volume shop use.
At 12 inches, this slide is the right length for shallower drawers: spice-pull-out boxes, narrow utility cabinets, shop organizer drawers, and the top drawer tier in a base cabinet stack where depth is limited. Full extension means that at full open, the whole drawer clears the cabinet face — a buyer at the back of a 12 inch box can reach every inch without tilting the drawer out. The hold-in anti-rebound detent earns its keep in shop and garage settings where vibration or a heavy close would otherwise send the drawer drifting back open.
The Ebony Black finish on the KV 8400 series is a dedicated color option, not a painted-over zinc slide. Steel members carry the black coating through the slide's service life indoors. Like all slides in this segment, the 8400B is a functional-finish product — it sits beside the open drawer box, partially visible, so the color read matters where the interior palette calls for it. The zinc versions of this same slide disappear against light melamine; the Ebony Black version is the call when the box is dark or when the hardware program runs black throughout.
Cabinet shops building dark-interior boxes or spec'ing for a black hardware package will get the most from this SKU. The non-handed format and Bulk-Pack quantity suit production environments — pull from the box, cut to sequence, install without sorting left from right. Contractors replacing slides in existing dark-interior cabinets will find the 12 inch length and 1/2 inch side clearance match the standard side-mount format. Homeowners installing a shallow utility drawer in a modern kitchen with a black hardware scheme can order a single pair from the bulk carton.
The 8400B carries a dedicated black finish, not a field-painted zinc slide. It is the KV 8400 series built in Ebony Black as a catalog color, and it holds up through normal indoor use the same way the zinc version does.
No. The hold-in anti-rebound detent is a mechanical catch that stops the drawer from rebounding open after it is pushed shut. There is no damper and no spring assist — the drawer neither slows into the close nor pulls itself shut. It simply stays where it is left.
KV recommends a maximum drawer width of 24 inches for the 8400 series. Build the drawer box 1 inch narrower than the cabinet opening to leave 1/2 inch of side clearance for each slide.
It can, but face-frame cabinets require support at the rear of the slide. Add the matching KV rear mounting brackets (sold separately) or use the series' face-frame mounting options — the slide itself does not include rear support hardware.
Bulk-Pack means the slides ship loose in a trade carton rather than in individual retail bags. Check the pack quantity on the product page to confirm how many pairs you receive per unit ordered.
Most drawer slide decisions come down to length, extension, and load rating — the Ebony Black finish is the detail that makes this particular SKU the right answer when dark-interior cabinetry or a black hardware program is in play. Full extension, a 100 lb rating per pair, and a stay-closed detent handle the functional side; the finish handles the rest.
