Hello, I am the engineer who makes this strap, and I will explain it in plain language even if you are new to strapping. This 2510 is a wide-format heavy-duty PET strap: 25 mm wide and 1.0 mm thick, with a rated breaking strength of 9,800 N. If that number means little to you, picture a strap that will not snap until you hang around a full tonne of pull on it. The point of this grade is not only strength but width: a 25 mm face spreads the force over a big area, so heavy
