Hello, We tend to use proper cable cushion/hanger hardware on towers, but in other places a zip tie is sometimes needed.  We had a ton of zip ties pop off before, and always see them breaking off when climbing towers with ties.  Luckily Mr.Project Farm has released a zip tie comparison video today: https://www.youtube.com/watch?v=XMfOwPuN0Ao I found it really informative, and you may too, if you're into such obscure things like performance of zip ties in outdoor environments and their failure modes under load. --Bart
