Discs for snowboard bindings, often referred to as mounting discs, are essential components that connect the bindings to the snowboard. These circular or sometimes uniquely shaped plates sit between the binding's baseplate and the snowboard, featuring slots or holes through which screws are inserted to secure the binding to the board. The primary function of these discs is to provide adjustability in the binding's position and angle, allowing riders to customize their stance width and the angle of their feet.

This adjustability is crucial for achieving optimal comfort, balance, and performance tailored to individual riding styles and preferences. Discs are typically made from durable materials like metal or reinforced plastics and are designed to fit specific binding and board hole patterns. With the evolution of binding technology, some brands have developed proprietary disc systems that offer enhanced adjustability and compatibility with their bindings, further optimizing the rider's experience. The choice and setup of these discs play a significant role in the overall feel and responsiveness of the snowboard setup, making them a key component in achieving a personalized and effective riding configuration.
