 QCB Cabinet Brackets

QCB Brackets add stability
to large multi-cabinet systems

There are 2 sizes of brackets. Small brackets connect small top cabinets to other top cabinets, or to large tilted cabinets. Large brackets connect a large tilted cabinet to a keyboard garage.

Screws and fiber washers are provided in the kit. Fiber washers go under the head of each screw, and between the bracket and cabinet for each screw.

Cabinet Feet
Cabinets that are stacked and mounted together with QCB brackets typically have their rubber feet removed.

Pre-Drilling Cabinets
If your system was ordered with brackets, we likely predrilled the cabinets for use with the QCB brackets. If not, you will have to mark the cabinets using the brackets as a template and pre-drill the cabinets. This makes the screws easier to install and prevents splitting of the wood.

Stack, drill, and mount the brackets on only one cabinet at a time.

Align the cabinets so they are even across the front and on each side. Place the bracket where the cabinets come together and visually align them in the center of the seam. You can also use a ruler and tape for a more precise alignment. Use a felt marker to mark the middle of each screw hole. Remove the bracket and predrill the holes with a drill bit that is smaller than the minimum diameter of the screws.

Mounting Cabinets Together
Mount the brackets on only one cabinet at a time.

Put a fiber washer under the head of each screw, push the screw into the bracket mounting hole, then put another fiber washer on to the screw. Do this for each screw. Then place the bracket on the cabinets and use a screwdriver that fits the screw head correctly.

Top-Heavy Systems
If you have a large system that is top-heavy, such as when a tilted cabinet is turned upside down on the very top of the stack, it's important to attach the system to a table top to prevent it from tipping over.

DC Power Cables
Multi-cabinet systems typically share DC power from a single power supply mounted in the bottom cabinet. QIC inter-cabinet cables transfer DC power between cabinets. Exactly how this is done depends on the configuration of the system, but typically the cabinet receiving DC power does so with a Q103 DC Power Module. The Q103 module can then act as an output to the next cabinet in a daisy-chain fashion.

This picture shows a multi-cabinet system sharing power. A Q137 module in the bottom cabinet acts as the source of DC power which is delivered to Q103 DC Power modules in the other cabinets using QIC cables.
