Construction & Rigging: Scaffolding, safety harnesses, towing.
Outdoor & Adventure: Climbing gear, zip lines, rescue operations.
FAQ
Q1: What's the difference between a key pin shackle and a screw pin shackle?
A: A key pin shackle uses a removable pin secured by a nut or cotter pin, making it more secure for heavy loads than a screw pin shackle.
Q2: Is 316 stainless steel suitable for seawater use?
A: Yes, 316 stainless steel is highly resistant to saltwater corrosion due to its molybdenum content.
Q3: How do I determine the correct shackle size for my application?
A: Match the Working Load Limit (WLL) to your load requirements and ensure the shackle's diameter fits your rigging setup.
Q4: Can the key pin loosen over time?
A: Properly tightened nuts or cotter pins prevent loosening; regular inspection is recommended.
Q5: Are custom sizes or markings available?
A: Yes, OEM requests are accepted (minimum order may apply).
