C.H. Hanson's heavy-duty flagging tape is an excellent choice for laying out boundaries. Choose from a variety of patterns and colors. This strong tape is constructed from weatherproof poly vinyl chloride that is designed with toughness to hold up to harsh outdoor conditions. Our non-adhesive, non-conductive poly vinyl tape has added plasticizers for increased elasticity. Fade resistant colors quickly catch people's eyes and alerts them of the danger or caution that must be taken.
