Clamp size listed is the actual inside diameter of the clamp, not the corresponding hose size. Always select a clamp size larger than the outside diameter of the hose with which it will be used.
When installing multiple clamps per hose end, offset the buckles by 45 or 90 degrees so that the buckles are not aligned

** 13/16″ and 1-3/8″ ID clamps are 3/8 wide and require a tool capable of 3/8 and 5/8 clamp widths
