Wooster Paint Brush Lock Jaw Adapter

Really good quality. Adjustables are good on it compared to other alternatives.

Once you get used to it, its great for those difficult to get areas. Recommend a bit of practice first.

This was inexpensive and great!
I had to paint an inaccessible fascia that needed scaffolding or a cherry picker to safely reach by hand. I already had an extending pole so this just screwed on the top. It's a bit of a pain dipping the brush into the paint when its on the end of a long pole, and you have to beware of drips as you 'wave' the brush around in the air, but it was a whole lot cheaper than any of the alternatives.
