New England Safety Blue Hi-Vee. This old school favourite is an excellent arborist climbing line with high strength, flexibility, and safety features. The high-visibility Safety Blue has the added safety of being very easy to see, even when dirty. Safety blue is treated with a special coating that helps to increase abrasion resistance and extend rope life. Safety Blue is a 16 strand single braid rope made from polyester and polyolefin fibers. Safety Blue Hi-Vee is spliceable.
