About this 90 Degree Elbow

A 90 degree elbow turns your duct a full right angle for a tight corner or a drop straight down. The smooth inside curve keeps the air moving better than a hard miter joint.

Set both ends the same size, or step sizes across the bend. Each end is a friction fit that pushes on with no clamps in most setups.
