Review: As Advertised - I bought this for my laser.. I vent out the window and it gets cold here in the winter and I wanted something to stop the cold air from coming through the vent and fan back into the laser... some one in the WeCreat 45w Vision Pro laser group I belong to suggested that I get a Blast Gate .. I ordered this one and it works perfect .. Highly recommend

### ⭐⭐⭐⭐⭐ Works !!
*by S***N on January 27, 2025*

This was needed to connect my CNC to my wen dust extractor, had a 2 inch hose up to a 4 inch opening which has to connect to another 4 inch inlet on dust collector, both have 4” OD, and as you can see from pic, it worked perfectly. The thumb screws are a bonus, makes installing it a breeze. So if you’re looking for something to connect 2-4” hoses together, this is what you need . Arrived exactly when it said. Power tech is actually a decent company. Haven’t had to work with their customer service, so I cannot speak to that but their products are decent.
