A fully adjustable weight system that alows you to tune the stabilizer to your needs. The aluminum tube is perforated to aid in stabilization during regular conditions and wind. When the wind moves through the perforations it flows in a circular motion inside the tube before exits, thus creating added stabilization. A heavy neoprene gromment is at the base to absorb the initial shock and distribute the energy. A large neoprene cap buffers the forward movement of the shock and is also used as a protective end cap. Stabolution is the Solution!
