Thank you for viewing our range of Elbow Joints for curtain poles. These curtain pole joiners allow for a variable angle between the poles. These joiners are very useful when hanging curtains in a bay window or another recessed area that may involve several poles running at various angles. We have one of the largest online collections of Curtain Pole Brackets & Connectors HERE at Poles and Blinds. If you can't find what you are looking for, please contact us for further help.
