Line Strength Test

Braidman shows you how FINS Braids test the strength of braided fishing line and how to understand FINS labels tensile strength on a package.

This tensile device is used is to make sure that FINS products stay within the range of tolerance needed to meet FINS exacting standards.

Beginning by lacing up a line to do a tensile test, he then zeros it out to calibrate the machine. He anchors two lines above and below. Then the knots are isolated by wrapping it five to six times around the one-inch diameter steel rods. When the machine starts, it's going to elevate to the top and register on the load cell the pound test (or the actual load in pounds).

In this example, Braidman is testing 15 lb. FINS 40G. On the label for this 40G braided fishing line, it says the average break is 26 pounds but this particular line actually breaks at 30.

Why use a lower line strength on packaging?

This 15-pound 40G actually broke at 30 pounds but we don't call it 30-pound line for two reasons.

• First, we always like to be safe and make sure that we're not overstating what we've got on our package.
• Secondly, we factor in your knots. You can't fish without a knot and when you tie a knot in this product it's going to bring that down at least 30 percent, depending upon your skill of tying knots and what you chose to tie it to.
