Sailing Coil Winding Jig Black
There is a threaded hole where the coil peg fits. The thumb screw is made from stainless steel and is used to secure the coil wire.
You can store the pegs inside the coil jig when they are not in use. This is a great little feature that helps you to not lose the pegs when they are not in use.
There are three coil winding pegs that are included with the jig. These allow you to wind the coil wire into different sized coils so that they will perfectly fit your RBA or RDA. The coil pegs are 1.55 mm, 2.36 mm and 3.17 mm.
