The Fathom Third Hand and Corner Guides allow you to quickly and easily assemble and dissassemble the Aputure Amaran F21 and F22 flexible light panels without having to bend and reshape the mounting arms. 
 
Saves you time and prolongs the life of the mounting arms.
 
Additionally, by maintaining the shape of the arms, you can ensure your F22 and F21 panels will remain attached to the arms, especially when underslung and mounted facing downward.
 
The primary purpose of the Corner Guides is to prevent the ends of each arm from snagging on the velcro in each corner when assembling.
 
Each unit includes 1 Fathom Third Hand and 4 Corner Guides.
