This pleated blind is made of 100% polyester. It is height adjustable with two aluminum rails with two control handles and four premium clamp supports for easy installation on the window sash. The adjustment range is approximately 6-30mm. The clamp carrier is made of UV-resistant plastic, and as it is a pleated blind, it can be fixed even on a tilted window. The rails include a cover strip to protect against dust. The clamp carrier is only suited for windows with a rubber seal.
