I wish there had been product reviews on this item before I ordered it. Reviews are helpful. The product description states these ties are 90# tensil strength but they are not near as strong or heavy as the 75# tensil strength tie wraps that I already have. Seems like they are no stronger than 40# or 50# tensil strength. I will keep them for general purpose but will buy some that are more heavy duty for the project I bought them for. There was nothing on the package that stated the tensil strength at all. It was only in the online description. I think they were wrong about the 90# tensil strength. Hope this helps someone who is thinking about buying these for their strength.
