Reconnecting a clothes dryer to an outside vent
I bought the 2 clamp set (rated at 4.8 out of 5) to reconnect a clothes dryer to an outside vent. I also purchased Deflecto Supurr-Flex Clothes Dryer Transition Duct - 4" x 8' F0408B/4, and Dr. Rooter 2.5 in Aluminum Tape for Dryer Vent Duct Repair. I'll be moving the dryer back into place early next week.

Very sturdy clamp with rock tight connection.
Very sturdy clamp with rock tight connection. It was very ease of use and installation was a breeze. The fit was perfect since it had several different sizes due to the worming mechanism. let's just say that my exhaust clamp rattle was fixed permanently by using this to clamp the loose connection down to the tailpipe and I could not be more pleased.

Perfect Fit and Heat-Tested Durability.
I'm really happy with this Imperial 4-inch Metal Worm Gear Clamp. The fit was excellent, making the connection strong and secure right away. What truly impressed me was its durability. I used it to join parts of an exhaust pipe, and it held up perfectly against the high heat. This clamp is clearly built tough. It was also incredibly easy to install. The gear mechanism is smooth and works reliably. If you need a clamp for a demanding job, especially one involving heat, I highly recommend this one. It's a great quality product!
