Threads look a bit nice. The threads on my telescoping pole are well defined and this sanding pad fits my pole well. I actually have one Attached piece of plywood to this sander and then covered the plywood with a towel to clean some inaccessible windows and this sander worked great I plan to use it for its intended purpose scraping acoustic ceilings it should work great The Rubber backing is pretty solid and the sandpaper holders work great.
