Alan won't those booms fit the Nikro vac (spelling?)
The booms have a 2" opening and will accept any vac that can be matched to this. I have used 1.5" vac hose with a hose cuff that upsizes to 2" at the end and it did fine.
I have seen folks use duct tape to take up the extra space of using a 1.5" cuff. As long as the seal is there, and the vac has enough strength, then it will work.
