Type B corrugated elbows feature a ribbed design that provides 3x more structural rigidity compared to smooth elbows. The corrugations act as reinforcement beams, preventing collapse under heavy snow loads and maintaining shape during extreme temperature fluctuations. This professional-grade construction is essential for Pacific Northwest weather conditions.

The 75-degree angle provides the optimal balance between water flow efficiency and structural installation requirements. It allows sufficient water velocity to prevent clogs while providing enough angle change for most wall clearance needs. This angle is the industry standard for residential and commercial applications.
