It's not exactly high performance at 990 degrees Fahrenheit and 6.7 cfm at high speed, but it does for a smaller channel of 1 /2" to 1-1/4" I can do a standard box shift in about 5 minutes while covering the end of the tube to retain heat. It also works well for heat shrink cable lugs and UF heat shrink connector kits when working in a trench. The simple tool comes with two nozzles, a heat shrink deflector and an expander. It has two temperature ranges, but I mostly use high settings. You really need to use a 5Ah battery or more with this heat gun or you'll have to change it frequently. Overall, it works well for small jobs, so I'm happy with it. This tool does not come with a belt hook but has slots for a DeWalt N268241 belt hook and is easy enough to install. All I had to do was drill a hole for the bolt and use a spare nut from one of my other Dewalt 20V tools. I also used a dremel with a 1/8" round burr to remove a small amount of plastic from the battery compartment to countersink the nut.
