Magnetic quick-swap dust collection system for 2.5" hoses. Includes connectors for the hose, plus ones designed for my mitre saw, table saw and cleaning nozzle (but could be used on any 2.5" tool). For a bonus, I included the y-tube I created for my router table, which has two 2.5" ports. Designed to use six 10x3 neodymium magnets that snap in place - no glue needed just some pressure.
