Black Rapid"s Wrist Strap combines BlackRapid"s patented ConnectR (CR-2) hook with a comfortable and secure wrist strap. The wrist strap is designed as add-on for BlackRapid"s R-Strap systems. It hooks naturally to any camera with an existing BlackRapid FastenR (sold separately). The strong wrist strap is smooth for comfort, and has an integrated corrosion-resistant anodized ConnectR hook. The carabineer style hook has a twist lock on the gate, for added security.
