I have constructed and used these braided loops for more than 20 years primarily for saltwater fishing.  These loops are custom-made with Gudebrod 50# test braided mono.  Properly constructed and properly attached DOUBLE-CATCH braided loops like these simply will not fail!  Much stronger and more reliable than the common single catch braided loops, with the heat shrink tubing, you see in the shops.  These store-bought loops are not in the same league!  These loops are widely used for everything from stripers to large tarpon and sailfish.

Many uses for these braided loop connectors:

Dan Blanton, noted saltwater fly fishing outdoor writer, an early proponent of braided mono loops, had this to say in his article Getting Looped:

"There are a couple of ways to make a loop in braided mono. There is what we call a single-catch loop and a double-catch loop. Trust me, use only the double-catch loop. It will not slip. Single catch loops frequently fail."  and  "Made properly they will slip through the guides like ladyfish slime, will hold the largest tarpon or billfish, and will make connecting fly lines to backing, shooting heads to shooting line and leader butts to fly lines easier and more efficient than ever before." 

  You will receive:

• The quantity you specify of Double-Catch 50# test Braided Loops.  (10" overall length)
• A coil of 10# test mono to use for nail knots.
•  Simple directions.
