Spearit NTR Inserts: Wishbone Assembly

1. Cut the ends of a 12in(30cm) piece of wishbone cord at an angle for easier insertion. We recommend Spearit 1.9mm or 2.5mm Spectra wishbone cord.
   .
2. Thread two NTR Terminal Inserts on to the cord, butt first, from opposite ends.

   .
3. Tie a simple over hand knot in one end of the cord
   
   Figure 3
   .
4. Postion and tighten the knot 1/2in(13mm) from the end of the cord.
   
   Figure 4
   .
5. Tie a second overhand knot in the opposite end of the cord.
   .
6. Position and tighten this knot 3 inches (for 4.5 inch wishbone) from the first.
   
   Figure 6
   .
7. Trim the excess cord 1/2in(13mm) from the second knot.
   .
8. Unravel the strands of the 1/2in(13mm) tails at both ends of the cord.
   
   Figure 8
   .
9. Melt the unraveled strands with a heat gun and roll them into a tight ball against the knots. It is highly recommended that this step be performed only in a well ventilated outdoor area using protective leather gloves.
