I have an slx-25 and the end cap is on solid- it must be glued. I was wanting to buy and extra few sections so that when I need a longer pole (only every 6 weeks)- I could just add and remove the sections as needed- save me buying a 35ft pole! As I'll need to remove and replace the end cap I was wondering if I buy them from gardiners whether they fit on snug? Or do they have to be glued? Obviously for my situation- glued is no good. They need to be on firmly, but able to pull them off when needed. Anyone bought any? Or know?
