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

Very happy with this product. I can't tell you how long I've been looking for an adapter that will fit my Dewalt table saw, Ryobi disc sander and Bosch router to my 4-hose JET dust collector. All of these tools appeared to come with a 2.27-inch ID port. I've tried everything and finally this one suits them all. I will be buying more to work out the rest of the tools. Be sure to buy!

The OD of the narrow end is 2 1/4 inches, which is the size of a large Shop Vac hose. Therefore, to use this, you need a screed. In fact, the large end's OD is the same size as a 4-inch hard-galvanized duct, so you'll need a coupler on that end as well, unless you're connecting it to a dehumidifier's flexible vent hose. I bought this and then had to go to the hardware store to buy two more pieces to make it work! :(

Quality is ok although the necks could be longer I found this. I have to heat it with a heat gun to get it bigger or smaller, but I backed out anyway.What really worked for me was a $6.98 rubber case at the big blue store (Fernco 2" rubber case P3000-22, store number 792021). It comes with a Metal sleeve supplied which I took out the rubber boot and used clamps to hold it in place The Ridgid hose then goes straight into the rubber boot Problem fixed.

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…

If you have a 2.5" vacuum cleaner, you would buy it for a 4" vacuum cleaner , right? Well it is exactly the same size as your vacuum hose and won't fit over it. I remembered that I had bought one of their products before and it broke before I could even put it on. The sticker is not a sticker, which can be peeled off you have to soak in solvent to get it all off which is great if you don't I don't value your time can't say enough good things about this company's vacuum nozzles just stay away…

This adapter is perfect for what it does and where it simply fits (or doesn't fit). The 4" end is a male connector that accepts a 4" dust collection hose. The hose is placed directly on this piece and fastened with a clamp. Now for the little ending, which caused some confusion. If your male hose end is 2 1/8" OD and your tools are 2 1/4" ID, then you know it's a 2 1/8" fitting. Go check it out - then this. For example: I have an enclosed guard that I made for my 12" ShopSmith grinding wheel…
