Carabiner Hook for Camera Strap, 1/4 inch Screw Connection, with Anti-Drop Lock This is a metal hook for attaching shoulder straps or sling belts to the tripod hole (1/4 inch screw) on the bottom of single-lens reflex cameras and mirrorless cameras. By hanging the camera upside down, the stability during carrying is increased, and it can be used like a quick-release strap, allowing you to quickly take a shot. The hook's opening and closing section has a screw-type locking mechanism to reduce the risk of accidental detachment and dropping during movement. The size is approximately 6cm in total length and approximately 4cm in maximum width. The width of the rectangular hole for the strap is about 2.6cm, so it supports belts up to about 2.5cm wide. It can be attached to almost all cameras with a standard 1/4 inch tripod screw hole. A thick rubber packing is attached to the screw seat, preventing scratches on the bottom of the camera and preventing loosening. It is in near-new condition. It is made of metal and has a solid weight and rigidity. The product includes only the carabiner hook and the connecting screw as shown in the photo. #CameraStrap #QuickReleaseStrap #Carabiner #Hook #1/4Screw #CameraAccessories #SLR #Mirrorless #AntiDrop
