CUT TO A CUSTOM LENGTH? MAY SAVE ON SHIPPING

HOW WOULD YOU LIKE IT CUT?

Some cutting jobs allow us to use ground shipping rather than LTL, yielding significant freight savings. A customer service associate will contact you to confirm the cut list and shipping and freight costs prior to finalizing your order. eg - 4 cuts per stick x 5ft per section
