ISO 2" automated blast gates

[JoeCallahan]

I finally finished connecting the table saw to my shop vac dust collector. I'd like to replace the current blast gate with an automated one, but can't find one smaller than 4 inches. I considered trying to make do with that size, but don't want to drop $100 on a gate. Any suggestions will be greatly appreciated.

Leave it as manual. Never did see the need for those air operated or electronically operated gates unless you have a huge shop and many tools connected to the huge dust collector. That dust collector is not designed for multi tools. Save the money and spend on other things.
