Zusammenfassung:The present invention relates to a root bushing, a root bushing insert, a wind turbine blade and a method of manufacturing the wind turbine blade. The root bushing comprises a bushing housing with an outer surface and a main bolt cavity. The outer surface is provided with an outer threaded portion arranged at a distance from the first end. The main bolt cavity has an inner threaded portion arranged at a distance from the first end. A cap element is positioned within the bushing housing at a distance from the second end and separates the main bolt cavity from a root insert cavity. The root insert cavity has a curved inner surface, which enables resin to fill the space between the inner surface and the end portion of the insert element.
