These are clearly incorrect sizing. I have 4 legal 2" clamps. These are 1/2" clamps! They appear to measure the full length with no opening. I bought the correct size locally.
Pros
Material: These steel spring clips are made of nickel-plated steel with red rubber grips on the handles and tips for durability and rust resistance. PVC coated tips and handles to protect delicate surfaces with non-slip grip.
