The Pole Position Tungsten Putty Bar from POLE POSITION is the ideal tool for creating different types of pop-up rigs. The bar is designed in such a way that it fits nicely on crimps and various knots. Because the bar is provided with special ribbing, extra weight can be added by applying Tungsten Putty to it. This way the ideal counterweight can be chosen for Spinna/Ronnie rigs and other pop-up presentations and a stiff or flexible boom section is perfectly held on the bottom.
