The poles are oval shaped, providing precise control over the direction of the blade (especially important when cutting high) The oval shape also gives strength and rigidity to the pole, reducing the chance of poles bending and breaking.
The poles have a double locking system. There is a pin/button which locks the poles in place and a clamp that overlocks the poles together. The two locking systems are designed to work together and protect each system from damaging the unit. This dual-locking system allows 100% of the effort at the handle to be effectively transferred to the blade ,which is metres away.
Spring-loaded locking buttons allow multiple length adjustments and safety-friction clamps hold the extensions firmly in place. The base pole has a pole-end shock absorber to protect the pole if the pole slightly impacts the ground. It also has a comfortable rubberised overgrip which ensures good hold and control.
