The Manfrotto Tilthead Shoe Lock is a mounting bracket that allows you to use an umbrella with a portable flashgun on a stand. The Tilthead's screw locking shoe mount will accommodate most flashgun hotshoes, and the umbrella socket allows you to use a bounce or shoot-through umbrella. The Tilthead fits any stand or other support device with a standard spigot treatment. The ratchet-style pivot on the Tilthead eliminates any sudden movement when the screw is tightened.
