Harold:
The only thing I ever saw on a bag of Ty-Wraps (T&B) was something to the wording of flame/smoke spread, that was on a bag of 'purple' or 'maroon' T&Bs; that was at least 5-7 years ago at a car dealer new bldg.
Telco/data guy had them; EC went to pick up some at Cooper...till he found out the $$$; he came back with ss ty-wraps; no issues.
