    Abstract: A scaffold access ladder bracket assembly is shown and described. The assembly can be used to attach an access ladder having side rails to a scaffold. The assembly includes a bracket body that includes bent portion terminating in hooked ends. The hooked ends wedge the bracket body against the side rails. The assembly also can include ramped portions connected to the bent portion and spaced apart from the hooked ends to create ladder receiving channels for receiving the ladder side rails. And the assembly includes a locking mechanism connected to the bracket body for lockably engaging the bracket body to ladder side rails. Also disclosed is a method of installing a scaffold access ladder on a scaffold using the assembly. The assembly provides a bracket assembly that requires no tools to install and/or dismantle in at least some instances (e.g., when the assembly is connected to a ladder), and thus, is easy to use and handle.
