Secondary Lint Trap w/ 4" Adapters

I was called to inspect and recommend whatever was necessary to fix a potential exhaust problem with a dryer vent. I found the long, twisty 4" round duct completely plugged. Not at an elbow or at a vertical spot, the whole run. About 40' with seven 90° elbows plugged up solid. It had to take a long time. I was able to find a closer exit with four 4" 90° long throat elbows, two clean outs and the secondary screen that's better than the dryers own filtration. I'm confident that your product, along with the extended brush will keep this customer happy.
