Review on 🔽 POWERTEC 70146 Eccentric Reducer: Black, 4-Inch to 2-1/4-Inch by Greg Harris

I bought this adapter to fit the dust hole on the back of the Bosch router table. Fits almost perfectly. I mean it fits but not tight. To ensure a tight fit I wrapped tape around the end that goes in the dust hole. I then connected the adapter to my 4" Y-piece with a Powertec clamp. This gearbox is exactly what I needed for my router table. It's durable and the right size for my needs. I like Powertec products because they offer quality products at a good price, they are not overpriced like some other well known branded products, the hose clamp I used is also a Powertec product.
