Les! I would not recommend using a nylon tie wrap for such important fastening purposes. Nylon, also known as "Polyamide" is not resistant to weathering. It will get brittle and fail. Depending on the amount of weathering and the mechanical stress on the tie wrap, it may take some years till this happens, but when it happens, you wish you hadn't used it. The nylons normally used for tie wraps are PA6 and PA6.6 For further info on Polyamide etc.: http://www.goodfellow.com/static/A/P.HTML I would recommend a stainless hose clamp or a stainless tie wrap. bye, Ralf. > I wrote last about adding a nylon tie, this I did.
