4" FITTING - ELBOW W1017

Installed this elbow to route my dryer duct around a corner and it clicked right into the existing 4-inch pipe. The fit was snug but not impossible to slide on.

Finally found a 4-inch elbow that doesn't crush when you tighten the clamp—this one held its shape perfectly. Snapped right onto my existing ductwork with no wrestling, and the airflow feels noticeably smoother around the corner. Solid buy for anyone fixing up a basement ventilation run.

The bend radius on this elbow is just right—it fits snugly into my ventilation run without taking up too much space. Airflow seems smooth through it, and the 4-inch opening lined up perfectly with my existing ductwork.
