The Black Rapid Lockstar Breathe Carabiner Protector is compatible with
Black Rapid straps that feature a CR-3 or CR-4 ConnectR locking
carabiner. By folding over a CR-3 or CR-4 ConnectR, the Lockstar Breathe
prevents unintentional user contact with a CR-3 or CR-4 ConnectR that
could cause it to accidentally unlock. Additionally, it blocks the metal
surface of a CR-3 or CR-4 ConnectR from scratching a connected camera.
This is a pack of two plastic carabiner protectors.
