If you have a multipole from Ionics then simply follow the instruction that come with the G-Fit for fitting (tools needed 1x 9mm drill bit to drill through the top of the plastic fitting to convert it to a hose through end fitting).
If you have any of their other poles with their gooseneck fitting on the end, you will need to remove this first (hacksaw off) then glue in one of the hose-through fittings below:


Then simply screw on the G-Fit and your choice of brush.
We have coming this week two new sizes of G-Fit in addition to the standard Gfit Type2 (17" reach), a slightly shorter reach Type2 (12" reach) and even shorter reach Type2 (6" reach). As soon as they come in they will be on the website. We have had these produced due to customer demand, many users do not like the plastic necks, but also do not need such a reach as the standard G-Fit hence the new choice in reach.
