POWERTEC 70108 4 Inch Blast Gate for Dust Collector, Dust Collection Fittings

POWERTEC 70133V 2-1/2" Blast GateThey work.They work BETTER if you drill a hole in the corner and mount the blast gates so that it sucks a little bit of air into the channel the gate uses and keeps the channel from filling up with dust. If the hole causes a noticeable whistle, try increasing the whole size a bit.

Easy peasy! Works like a champ, only suck the line u want, close off other.

Works really well cutting off one dust pipe toe open a second dust pipe

I used these when I built my HF dust collection system. For any DIYers or woodworkers, having good dust collection is key to keeping the shop clean. There's more expensive brands but these get the job done. I needed the 4 inch for the larger suction and they have worked great. They aren't heavy duty but so far I haven't had any issues.

The media could not be loaded. Not flimsy, and does the job. I'd buy again. The gate piece itself isn't a smooth ride up or down; it's a little bumpy. Not a major problem, though. I recommend these. They were cheapest money-wise out of the ones available at time of purchase.

I used this as a gate from my gerbils cage to their playpen connected with the 4 inch tubing. It works great for this and they love it. I can close the gate when it is time for them to stay in their cage. It is perfect for this purpose.

Finally got around to adding this to dust collect. Much easier that bending down to sweep to a dustpan.

I put about 8 of these on tools around my shop to connect them to a jet 1300 CFM did collector.On one of them, the plastic had split apart so the sliding gate would just fall out. I super glued it back together and it was ok.Big problem is that over the next 3-4 weeks they would no longer close all the way. I tried removing trapped dust with a tooth pick but it was too much work and not effective. You can see what happens in the picture. I took one apart so I could see exactly what was going on. Dust will get trapped and the gate won't close fully. If the small opening doesn't bother you then it's fine. With as many tools as I have connected to the system, that opening across all of them is equivalent to a fully open gate so it's not viable. I had to replace them all with gates that go both ways so they don't clog.
