Good if it doesn't clog
I have 7 of these blast gates for my 2.5" dust filtration network. They mostly work great! However, 2 of them got clogged up and would no longer close properly. Another reviewer here had the same issue I did. I tried using compressed air as well as an angled pick to try and get out the debris but it did not work. I ended up breaking the hot welds to get inside, but now that I've taped it shut again the gate doesn't stay put. Woodcraft is sending me replacements. So I guess to quantify this experience, there's a 71.4% chance you're going to love these blast gates. :)
Buy a self-clearing one
These were great for a month or so, and then dust collected in them. They won't close anymore, and with 2.5" system, only closing halfway really hurts the suction on your other machines. Go ahead and spend a couple extra bucks on the self clearing ones (I haven't actually tried these), and save yourself buying twice or regretting your first purchase.
Shop vac size dust collection system has limited power. Placing gates appropiately allowed me to maximize the suction effort thus improving efficiency
Very good Product
Product works just as expected and the seal is much tighter than expected for a simple plastic on plastic sealing surface.
