Zinc Plated Durability and a Sure Fit for the KV 8400 Series
The Knape & Vogt 8401 is a snap-on rear mounting bracket with an extended rear flange, zinc plated, designed to support the back end of KV 8400 series drawer slides in face-frame cabinet installations. Without rear support, the back of a side-mount slide floats unsupported behind the face frame — this bracket anchors it solidly to the cabinet interior.
Key Features
Extended rear flange reaches deeper into the cabinet to anchor the slide's back end against the interior panel, even in cabinets with a wider face frame setback.
Snap-on attachment locks onto the KV 8400 series slide without separate fasteners at the slide connection point, simplifying field installation.
Screw-on cabinet mounting secures the bracket to the cabinet side or rear panel with standard wood screws for a solid, permanent installation.
Non-handed design fits either the left or right side of the drawer opening — no matching, no handed-part confusion, and no chance of ordering the wrong side.
Zinc plated metal construction gives the bracket the corrosion resistance and rigidity to hold up through daily drawer use in a dry indoor cabinet environment.
Where This Bracket Earns Its Place
Face-frame cabinets set the cabinet side panel back from the front opening, which leaves the rear end of a side-mount drawer slide without a mounting surface at the back of the face frame. A rear mounting bracket bridges that gap. The 8401's extended rear flange is specifically shaped for the KV 8400 series slide profile, so the connection is tight and the slide stays in plane through the full range of travel. Cabinet shops and installers fitting KV 8400 series slides into face-frame carcasses should count one bracket per slide — two per drawer — and have them on hand before the job starts. This bracket is not a universal part; it is engineered for the 8400 series and should not be substituted into other slide programs.
Zinc Finish in Context
The zinc plating on the 8401 is a functional indoor finish. It protects the metal bracket from the humidity and condensation that cycle through kitchen and bath cabinets over years of use, and it keeps the bracket from staining surrounding materials if a finish chip occurs. The bright zinc tone blends with the zinc-plated 8400 series slide members themselves, so the hardware reads consistently inside the cabinet. This bracket is rated for dry interior environments — it is not intended for outdoor cabinetry or high-moisture applications such as open boat storage.
The Right Shop and Installer Scenario
Cabinet shops producing face-frame work in volume will want to stock the 8401 alongside KV 8400 series slides, since the bracket is a required component whenever those slides go into face-frame construction. For a kitchen or bath installer reworking existing face-frame cabinetry with KV 8400 slides, the 8401 solves the rear-support problem without modification to the cabinet box. The non-handed design means a single line item covers all positions in the run, which keeps the order simple and the parts count predictable. Designers and homeowners specifying KV 8400 slides for a renovation should confirm the bracket is included in the hardware list before the installer arrives on site.
Does this bracket work with KV slide series other than the 8400?
No. The 8401 is designed specifically for the KV 8400 series. The snap-on connection geometry is series-specific, and using it with a different slide program risks an insecure fit. Match rear mounting brackets to the slide series they are sold to support.
Do I need a rear mounting bracket in a frameless cabinet?
Generally no. In a frameless cabinet, the slide mounts directly to the cabinet side panel, which provides rear support along the full length. Rear mounting brackets are primarily a face-frame requirement, where the panel is set back from the opening and the slide's back end needs a separate anchor point.
How many brackets do I need per drawer?
One bracket per slide — two brackets per drawer. Each slide needs its own rear support, so order in pairs to match the slide pairs going into the job.
What screws does the bracket use?
The bracket mounts to the cabinet with standard wood screws through its screw-on mounting holes. Screw size is determined by the cabinet material thickness; check the KV installation guide for the 8400 series for the recommended fastener.
The Part That Keeps the Slide in Line
A rear mounting bracket is easy to overlook in a hardware order and frustrating to be without mid-install. The 8401 is the piece that keeps KV 8400 series slides tracking straight and staying put in a face-frame cabinet — get it on the order with the slides and the job goes together as planned.
