The non-slip loop knot
When properly tied, using the correct number of wraps for the diameter of the mono, braided or fluorocarbon, and properly seated it’s a 100% knot. It’s wise to check for chaffing on the loop portion of the knot after a catch and retie if chaffed.
The Non-Slip Mono Knot is extremely strong and does not slip like some of the other loop knots. It’s very important that you follow the wrap counts for maximizing its strength: 10- to 12-pound test mono > five turns, 15- to 40-pound test mono > four turns (shown), 50- to 60-pound mono > three turns and 80 to 100-pound test mono > two turns.
NOTES: For braided lines use six turns.
Fluorocarbon users increase the turns compared to mono. They also seat the knot very slowly as fluorocarbon tends to break when jerked because of brittleness. However, once the knot is pulled tight, it holds and has very little decrease in strength from its original test.
