• Pin: A steel bolt that spans the two shackle ears.
• Shoulder: The part of the pin that contacts the ear when fully threaded or engaged.

The dimensions of the shackle are approximately 3 inches x 3 inches x 5/8 inch. It is essential to ensure that the selected shackle meets or exceeds the working load limit (WLL) for the intended task and is compatible with the slings and rigging hardware being used.

Safety Features: To ensure safety during use, the snatch block features safety pin holes. These holes allow for the insertion of safety pins to secure the shackle and prevent accidental disengagement. The safety pin holes have a size of 1/2 inch, and the quick-release size of the safety pin is approximately 3 1/4 inches x 1/2 inch when fully extended.

Overall Dimensions: The snatch block has dimensions of approximately 7 3/4 inches x 5 inches x 3 1/4 inches. These compact dimensions make it convenient to handle and install, while still providing robust lifting capabilities.
