Review on Versatile Stainless Steel Duct Clamps by Matt Weber

This is great, but be careful! cut yourself! There are no warnings on the packaging. Still, a great buy and a good product. My instinctive caution comes from working with the X-ray tube body counterbalance springs. Warnings are taught in the Training School. Length 12-13 feet Razor-sharp feathers have been reported to decapitate untrained technicians. Not sure what cleanliness means in the star rating so I gave it a 3.
