POWERTEC 70108-P2 4-Inch Blast Gate for Dust Collector, Dust Collection Fittings, 2 PK

Easy to install worth the money.

They work as expected. I have some concern about their longevity. The slides are stiff and difficult to open. The slides also flex, which will likely lead to material fatigue and fracture.

I purchased two of these to place on the "Y" adapter at the input of my 2hp dust collector, one to my table saw and the other to move between band saw and other tools. One of these closes completely, but the other won't close completely so the suction to the table saw is diminished to where the overhead dust collection isn't effective. I've tried to clean out the channels of any possible debris with no success. The other is fine, but I'm going to have to replace the one that won't shut all the way.

My whole system is powertec and I have had zero complaints. Everything is durable , very well made and top knotch plastic. Gates slide with ease and clamping to these gates are easy. 10 stars

I've had these for a few years now. As time goes by, the channels fill up with dust and the gate no longer closes all the way. Not sure if it's how I have them installed or just a bad design. Looks like there's better (more expensive) ones out there. I may give those a try instead.

it works good for what it is little pricey thou.

Bought this with the idea that either tue ID or the OD would fit on a 4" pipe... No such luck... Even the travel of the gate is less than 4", which makes my 4" stroke linear actuator incompatible...

Fit good. Open and close easily , have made my time better

My husband needed this product and he is very happy with it and it came very quickly in the post. Thank you Amazon.

Bit flimsy but it does work

Nothing fit together, I ordered several fittings and y's etc. I order an adapter and you would think it would fit onto the Y, or the Gate, but NO everything are the same size, so you need a coupler, but they don't sell a coupler, so now I either need to use a 4" piece of flex hose, (which makes the joint weaker) or I will need to design and print my own with my 3d printer.

No gastes tu dinero en esto, se obstruyen y las puertas no pueden cerrar hasta abajo dejando una rendija por la cual tienes mucha perdida y no creas que es facil limpiarla simplemente es imposible, basicamente es un prodcuto pesimamente diseñado. guarda tu dinero

Not amazing quality but they do the job. I bumped one while putting my system together and it came completely apart. I just carefully superglued the joints together and it’s bulletproof now. Did the same with the rest just to be safe. One of them doesn’t like to stay in position so I just threw a small spring clamp on it, does the job just fine.
