Where there are only a couple of wires {less than 12 mm diameter overall). • Make a single lock stitch on both sides of the breakout. • If the breakout is to be laced, use a starting knot and lace as normal. Method 2. On larger breakouts more than 121 • Make a double lock stitch before and after the breakout. • Lace the branch starting with a cable branch tie. • Where the wires fan out to go to a sub-assembly or connector, use a double stitch before each wire. 55 5. 4. 1.
