Chris, If using black nylon ones then I'd add that you use the ones with the metal "catch tooth" (for lack of a better term) as opposed to the ones with a plastic catch tooth. There is a price and quality difference.
I get my stainless steel ties from a local supplier. I'd have to check the mfgr. I share Augusts request for firsthand experience with failed black nylon cable ties, please. benn Sent from a 'smart' phone, with touch screen keys. Please excuse shortcuts and typos.
