We have changed the values of "Actual effective length depending on inclined angle of workpiece" for the following products based on the dimensions shown in the catalog. In this regard, please be sure to check the interference with the actual product before use. Please refer the values of the actual effective length based on the new calculation, although there is no interference with conventional values because they were based on tolerances of each product.
Please refer to our website for the new information.
