Currently, we don't have plans to make a 4-inch Dust Boot. Our version with a 5-inch port is a big reason of why it performs well (more CFM).


Reducer Kit

We do offer a 5-to-4" Reducer Kit as an option under "Port". This includes everything you'd need to hook up our Dust Boot to your 4-inch ducting.


✨IF YOU CAN✨ make a 5-inch work, we highly recommend that as you'll definitely see less performance than what you see in our videos since you'll be losing quite a bit of CFM.


We estimate about a 22% improvement in CFM with our 4" Kit versus the stock boot whereas our 5-inch Port is an ~89% improvement.



6-inch Version


We won't say never but currently, we don't have plans for a 6-inch option either. We've tested it and the 5-inch is pretty ideal for most cases. The biggest issue with more volume is the brush doesn't withstand the airflow and sucks in.
