T-Works Pro Level Setup Board System
T-Works has introduced a new Pro Level Setup Board System to ensure your setup board is perfectly level when on inclined or uneven surface so you can get the correct geometry setup. To use it simply install the Mount bracket on the four corners of the setup board and then use the hexagonal wrench to adjust the bracket and setup board to the proper balanced state. The brackets can be used on boards up to a thickness of 20mm. Once the board is stable then you can adjust it to the perfect level state using level that is part of the set that is housed in a hard case.
