Review on 🌀 Whirlpool 4396037RP Vent Periscope - Optimal 0-to-18 Inch Extension for Improved Airflow by Don Devine

Great product. Using a traditional flexible dryer with my new deeper dryer didn't give me enough room to open and close the garage door. Very frustrating! This product did its job. I have about 2.5 inches of space. I couldn't find my metal shears so I used a rotary tool and a cutting wheel. Worked great cutting the vent to the right length for my setup. I left an inch of excess material on each end, which was then folded onto the block. I then sealed the ends and any gaps with aluminum tape. Without tape, the block will not be completely sealed. I recommend using masking tape. The installation took about 60 minutes. It's worth $20.
