WATCH OUT!My Jet JW1044 4" to 2 1/2" adapter arrived today. Because I needed one badly I paid $6.81 for the part and $9.99 for shipping BUT I needed an adapter that was 4" INSIDE diameter on the large end and 2 1/2" inside diameter (nominal) on the small end.The item I received, marked "JW1044", is 4" OUTSIDE diameter on the large end.THERE IS NO INDICATION OF THE TRUE, USEFUL, SIZES OF THE ENDS OF THIS ADAPTER IN THE AMAZON LISTING!WATCH OUT!
