The Tenn-Tex QuikTRAY C-280 is a screw-on rear mounting bracket designed to support undermount drawer slides at the back of the cabinet. Where the front of an undermount slide locks to the drawer box, the rear bracket anchors the slide's back end to the cabinet — a step that is easy to overlook and hard to work around when it is missing.
Undermount slides attach to the cabinet at two points: the front locking device clips under the drawer box face, and the rear bracket anchors the slide's back end to the cabinet interior. In a frameless cabinet, the slide's rear end can often fasten directly to the cabinet back panel. In a face-frame cabinet, the slide is set back from the front frame, so the rear end of the slide is left unsupported unless a dedicated bracket bridges the gap. The C-280 fills that role, giving the slide a stable anchor point and keeping the drawer running true through its full travel. Without rear support, an undermount slide can flex under load, causing the drawer to drift, bind, or wear unevenly over time.
The C-280 is a Tenn-Tex QuikTRAY series component. Rear mounting brackets in undermount systems are series-specific — the geometry, clip points, and adjustment range are engineered around a particular slide design and are not interchangeable across brands or series. Use this bracket with Tenn-Tex QuikTRAY undermount slides. The screw-on mount type means installation requires only the bracket, screws, and a driver — no press-fit boring or CNC template needed, which makes it accessible for site work and smaller shops alongside production environments.
Production cabinet shops running Tenn-Tex QuikTRAY undermount hardware stock rear brackets alongside the slides themselves, since every drawer in a face-frame run needs one per side. The box quantity of 400 aligns with that kind of volume purchasing. Smaller operations and finish carpenters working on face-frame cabinet installs will also reach for the C-280 when the slides are specified and the rear support hardware needs to be sourced separately. If you are retrofitting or repairing an existing QuikTRAY undermount installation, this is the bracket to match.
In most face-frame cabinet builds, yes — the rear end of the slide needs support from the bracket since the cabinet side does not extend to the slide's mounting zone. In frameless cabinets with a solid back panel, the slide may attach directly, but check the slide manufacturer's installation spec to confirm.
No. The C-280 is non-handed and works on either the left or right side, so you order one part number for both sides of a drawer.
No. Rear mounting brackets are engineered for a specific slide series. The C-280 is a Tenn-Tex QuikTRAY component and is not designed to fit undermount slides from other manufacturers or series.
The bracket position can be set during installation to align precisely with the slide's rear end, which helps accommodate minor variation in cabinet depth without forcing the slide out of position.
A properly anchored rear bracket is what separates an undermount slide that performs over years of use from one that starts to drift after the first season — get the C-280 matched to your QuikTRAY slides and the back of the job done right.
