This Builder's Best dryer venting kit is just what you need to route that hot, moist air out of your laundry room! The main part is an offset elbow, which is a 90-degree bend but designed to help you navigate tight spaces behind your dryer. It's a 4-inch diameter, which is standard for most vented dryers. The whole thing has a sleek silver finish. It's brand new, unopened in its retail packaging. The model number is 010155 (UPC: 0722048101654). This is a countertop installation type of item, meaning it's ready to connect to your dryer's exhaust port. It's compatible with various brands – check your dryer's manual, but it often works with Star and other major brands. Weighs only 0.24 lbs, so it's light but sturdy. Perfect for a dryer vent replacement project, especially if your old elbow is crushed or clogged. Makes installation way easier than trying to bend a flexible duct sharply. Get your dryer breathing right!
