With their rounded shape, Bow Shackles are designed to handle many different types of load from any direction. Features a captive pin which completely clears the opening of the shackle when open, recessed in a secured, flush position. The pin remains captive and will not fall out; no risk of loss due to vibration. With other shackles, the pin is not flush until you partially unscrew it. Ideal for rigging applications where single-handed operation is required. Constructed of corrosion resistant forged 316 stainless steel.
