Introducing the 4-Inch to 2-1/4-Inch Eccentric Reducer by POWERTEC.
This dust collection fitting allows you to step down from a 4-Inch hose to a 2-1/4-Inch ID shop vacuum hose, port, or branch lines. It's easy to use and offers a secure, quick attachment to your dust collector hose.  This dust fitting increases air velocity near the machine where it's needed most. Additionally, it features an off center alignment, this smartly designed reducer helps keep dust from gathering in your system.
 
PLEASE NOTE: This reducer is specifically designed to work exclusively with 4" and 2-1/4" ID port, it is NOT intended to fit or accommodate a 4" OD dust collection equipment port directly. (which would require POWERTEC 70149 or 70369 Flex Cuffs)
 
Heavy Duty Quality
We make our reducers utilizing premium ABS plastic material, which provides long-term durability with resistance to rust and corrosion. It's thick walls are intended to stand up to hose clamp pressure and the abrasive nature of woodworking and workshop dust collection.
