What is the difference between netting sizes/strengths?
The gauge of the netting (#12, #15, #21, #36, etc.) represents two things: the thickness of the twine and the breaking strength per twine. As you increase the gauge (#15 to #21 for example), you are increasing how thick each twine is and how much weight it takes to break the twine. Refer to the “Twine Size Comparison Chart” for specific numbers.
