This is an attachment set for mounting the board and frame. It is a non-penetrating type where the upper and lower bolts do not pass through, allowing the board to be mounted without hindering its movement.
The stopper restricts the extension of the bushing, supporting the flex of the board while maintaining a direct feel. The stopper also absorbs shear forces, which are the main cause of bushing breakage, almost entirely eliminating the risk of the bushing tearing.
This attachment is designed to be compatible with modern boards that have become wider and longer.
If there are structural issues or deterioration in the insert section on the board side, the insert may come out entirely. The bushing cannot be used alone without the stopper.
