These are not heavy duty cable ties! The largest (12 inches) is 1/8 inch wide and about 1/32 inch thick. I broke one with my bare hands. I weigh 150 pounds. I missed the tie when donning the outer fittings insulating pouch, which has two "smooth" metal bushings. There were no sharp/rough edges at all. To Seller: If you remove "Heavy Duty" from the title/description I'll be happy to update my review, but your description is already misleading.
