I had the white nylon hold back on my 13'
Bigfoot door. The wind blew it one way and then back the other way very fast, and broke the arm off, also pulling, the door apart, (the aluminum edge pulled out of the wood door core edge ) all is repaired. I thought if I replaced it I would buy the metal units that look like the nylon, but they are constructed with all metal parts.
