MagLock Round Adapter - Is the ultimate in quick disconnect hose adapters. It now comes in two sizes... 2.5" and 4" for all your home woodshop needs ;-)
This product comes with one round adapter part and MagLock Ring. Upon receipt, please super-glue the two pieces together to form a single part just like in the second photo.
