It’s a 4" connector so it probably should have it’s own " magnetic connector for 4" dust collector hose" thread, but oh well…
Thanks so much all of you for distracting me from the main game! In my excitement I ordered 8x6 magnets instead of 8x10 so I have left enough depth in the magnet sockets to double up if I need more stick. So far so good, in fact I’m super happy despite having successfully used the old “push the hose on and hope” method for 30years!
The magnets are a push fit, the bottom skin .8mm and the holes in the bottom so I can push them out again should I wish to. You can see from one of the pics that my “maker space” is just a bit too close to the living area of our house for comfort, so I’m a bit careful with dust!
