Turnbuckle Hook and Eye Crosby Type HG-225
A Crosby-type turnbuckle with hook and eye ends, made from carbon steel C1045, hot-dipped galvanized for corrosion resistance. Designed for tension adjustment in rigging, lashing, and towing applications where one end is frequently disconnected and the other remains fixed. Available in sizes from 1/4"x4" to 2-3/4"x24", with working load limits from 400 lbs to 34,000 lbs. The threaded barrel allows precise tension control, and the forged hook and eye ends provide secure attachment points.

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Turnbuckle with screw pin | The hook and eye version offers a more secure fixed end and easier disassembly at one side, while a screw pin requires regular inspection to prevent loosening |
| Turnbuckle with two hooks | The hook and eye design allows one end to remain fixed during re-tensioning, reducing the need to reattach both ends |
| Non-galvanized turnbuckle | Hot-dipped galvanizing provides superior corrosion resistance in outdoor and marine environments |
| Standard turnbuckle without stamped WLL | Stamped working load limit ensures traceability and compliance with safety practices in the field |
Use Guide
How To Use And Inspect Turnbuckle Hook and Eye Crosby Type HG-225
- Verify the stamped working load limit matches the calculated load before use
- Ensure the barrel threads are clean and free of debris before adjusting tension
- Use wrenches or spanners to turn the barrel evenly to avoid side loading
- Inspect the galvanized coating for damage after installation and use
- Retire the turnbuckle if the body shows deformation, threads are stripped, or the marking is illegible
- Do not exceed the maximum take-up length specified for each size
