Pole Level Universal fits all aerial Poles series.
This Universal Level will fit a pole with diameter of 28mm to 60mm and attaches using Velcro strapping.
Tip: when using a pole level set the level as precisely as you can prior to extending. As you slowly raise the pole watch for any bubble drift and correct. As with all all poles, especially Pole series 2 and Pole series 3 be extremely careful if you are attempting to correct the level at full extension.
