The BabySitt'r is a universal mounting system that works with any standard baby plate, from most known manufacturers including Matthews, Avenger, American, Kupo, and Impact. Securely and quickly mount baby plates to the BabySitt'r in seconds, without tools or screws. This is ideal for grips, gaffers and shooters that want to save time and space. Each BabySitt'r can still be used as a normal pancake/eighth apple. These units feature a spring loaded locking system and two different plate slots to accommodate a wide range of plates or for dual plate applications.
