The Wrist Strap with FastenR FR-3 from BlackRapidis the same as their basic wrist strap but includes the stainless steel FastenR FR-3. The FastenR FR-3 screws into the 1/4-20 tripod socket of your camera and swivels using the built-in high-strength steel ConnectR.
This is a tether-style, 9.4″ strap that allows you to hold your camera tightly in your hand without fear of it slipping out or being grabbed. The ConnectR is made with a corrosion-resistant anodized hook and has a smooth swivel motion with a positive lock to give you maximum positioning of your camera. The locking carabiner on the strap provides additional security against slippage. The strap is made from soft nylon webbing.
