Yes, that's right. I bought it to use on a plate joiner. Fortunately, I needed the smallest diameter (1"), so I did not cut anything off. Paid the same price. This is the only time I've had to buy the adapter as the plate joiner clogs it's exhaust port. I agree it's a high mark up for a plastic part.
Not sure what the holes are for but you do push to required diameter and it is not collapsible.
Either push in till size is met or cut it
The outside diameter, using my calipers, measures 2.497".
