how do I order multiple lengths of HIWIN guide rail with blocks?

Select the desired rail here: https://buildyourcnc.com/Item/mechanical-rails-HIWIN-Linear On the product page, enter the total "cut to order" length (in inches). Then call us to specify the cut lengths. Remember that our maximum length is 2000mm or 78.74 inches. Our phone number is located at the top right of each web page by hovering over the "Need Help?".
