X-JOINT’s for post-2014 model poles only.
There are 3 sizes of X-Joints; 180mm (7″), 200mm (8″) & 250mm (10″).
The 180mm (7″) X-Joint has one half longer than the other & is marked with an arrow (on the shorter end), when used, this must be installed at the top of the pole with the arrow pointing upwards.
The X-Joint features a special mechanism which expands/contracts to lock/loosen the pole tubes together. Please test this prior to assembly.
