Review on High-Quality Stainless Steel T Bolt Clamps - 23-25mm Size by Deejay Devarashetty

Bought to replace the cheap clamps that came with a recently purchased diesel heater. I tried to install on the heater exhaust pipe with a diameter of 24mm. The clamps had reached their closing limit and were not tight on the 24mm exhaust port. What!? Took my calipers out and found the minimum clearance was between 24-25mm. Not only are they useless in my application, they can be dangerous assuming they fit snugly. Carbon monoxide can escape through a poorly sealed exhaust port and kill you. Not good. I keep them for other projects but don't trust the seller's sizing.
