Made of soft polypropylene materials with an exclusive weave, ArborTie won’t cut into tree bark, doesn’t unravel like rope or string, and is easy to install. Fastens to any stake or anchoring system with traditional knots or nails. Also ideal for guying, it expands as the tree grows in caliper and thus prevents girdling. Break strength: 900 lbs. Color: Green. 3/4” Wide.
