Zinc Rear Mounting Bracket Built for KV 8417 and 8419 Face-Frame Installs
The Knape & Vogt 8403 is a zinc metal rear mounting bracket designed specifically for the 8417 and 8419 drawer slides, providing the back-end cabinet support those slides need when installed in face-frame construction.
Key Features
Series-matched fit — engineered for the KV 8400 series, specifically the 8417 and 8419 slides, so the bracket seats and secures exactly as intended.
Zinc metal construction — durable metal body in a corrosion-resistant zinc finish holds up through years of cabinet service.
Screw-on mounting — attaches to the cabinet rear with standard screws for a solid, adjustable installation.
Non-handed design — a single bracket version works on either side of the drawer run, simplifying ordering and installation.
Rear-mount position — supports the back end of the slide where the cabinet side is set back behind the face frame, the critical gap this bracket is made to bridge.
The Problem This Bracket Solves
In a face-frame cabinet, the cabinet side sits behind the front frame, leaving the rear of a side-mount slide unsupported unless a rear mounting bracket is added. Without it, the slide flexes under load, drawers rack and bind, and the slide wears unevenly. The 8403 attaches to the cabinet back or rear wall and gives the 8417 or 8419 slide a secure anchor point at both ends, so the drawer runs true from front to back. It is not a universal bracket — it is built around the geometry and hole pattern of the 8400 series and should not be substituted for rear brackets from other slide families.
Material and Finish
The bracket is stamped from metal and finished in zinc, matching the standard hardware finish of the KV 8400 slide program. The zinc finish protects the steel through everyday indoor cabinet use. Because this is an indoor cabinetry component, it is suited to dry interior environments.
Where This Bracket Belongs
Specify the 8403 any time 8417 or 8419 slides go into a face-frame cabinet. It is the hardware that completes the installation rather than an optional add-on. Cabinet shops running face-frame boxes as part of a production line benefit from keeping this bracket in stock alongside the slides themselves, since a missing rear bracket on an install day stops the job. Retrofit and replacement situations are equally common: if an existing 8417 or 8419 installation is binding or the slide has pulled loose at the rear, adding or replacing the 8403 bracket is the first fix to try before replacing the slide.
Common Questions
Does this bracket work with slides other than the 8417 and 8419?
No. The 8403 is designed for the KV 8400 series — specifically the 8417 and 8419 slides. It should not be assumed to fit other KV series or slides from other brands, since hole spacing and bracket geometry differ by series.
Do I need a bracket on each side of the drawer?
Yes — one bracket supports one slide, so a standard two-slide drawer installation requires two brackets, one per side. Because the bracket is non-handed, both brackets are the same part.
Is this bracket needed in a frameless cabinet?
Typically no. In a frameless cabinet the slide screws directly to the flat interior side panel, so the rear is already supported. The rear mounting bracket is a face-frame requirement, where the cabinet side is set back from the face.
What screws are needed to install it?
The bracket uses standard screw-on mounting. Confirm the screw size with the KV installation instructions for the 8400 series, as the source data does not specify a fastener size for this bracket.
The Right Part, Ready When the Slide Goes In
Ordering the 8403 alongside the 8417 or 8419 slides means the face-frame installation is complete from the start — no second shipment, no job delay while waiting on a missing bracket.
