This is an incredible product, excellent for stabilizing trees with staking materials. We learned of it from our arborist and it is simply the best product available. Ours were over 3 years old and showed no deterioration. Ordered more! Does not damage tree trunks and once removed, can be reused elsewhere. Also useful for securing a wide range of items besides trees and landscaping items! Very cost and time effective compared to other options we used over time like bungees, hose and wire, bicycle tire tubes, various twines and nothing works as well as these tree chain locks for our landscape and general purpose applications. All sizes are very useful. Service at AMLEO also superior.
