The Flolight 11" Articulated Mounting Arm comes with a hot-shoe adapter that lets you use the Arm in three ways.
With the adapter attached, the Arm will have a hot-shoe on one end and a 1/4"-20 screw on the other. With the adapter removed, you'll have a 1/4"-20 screw on both ends. And removing only a part of the adapter, the lower part, will leave you with a 1/4"-20 screw on one end and a 1/4"-20 screw-hole on the other.
