The Bogen/Manfrotto spring clamp will attach your flash to about anything, from pipes up to 1.6", or stands or arms that have a 5/8 in top, or 3/8" thread. This is simply a must have for anybody using wireless flashes. It is really easy to adjust your flash to any angle you could think of. The flash attaches to a cold swivel shoe, that is ball linked, for easy adjustment to any angle.
Price: $54.95 USD
Once you have tried one, there is no way back. I have 3 of these spring clamps at the moment, and more to come soon. These babies are real easy to work with, and they attach to most anything. A must for people with multiple wireless flashes.
