Key Benefits
What Crosby HG 228 Gives You
- Jaw-to-jaw connection eliminates the need for extra hardware like shackles or eyes when attaching to fixed points
- Drop-forged carbon steel or stainless steel construction resists deformation under repeated tension
- Hot-dipped galvanized finish provides corrosion resistance in marine, outdoor, and industrial environments
- Adjustable length allows precise tension control in lifting, securing, and stabilizing applications
- Standard 5:1 design factor ensures minimum breaking load is five times the working load limit
- Available in multiple sizes and capacities to suit overhead lifting, cargo lashing, and towing
- Compact design reduces bulk compared to using separate turnbuckles and connecting shackles
Application Scenarios
Where Crosby HG 228 Is Used
- Overhead lifting setups where tension must be adjusted between two anchor points with no fixed length
- Cargo lashing on trucks and trailers using multiple turnbuckles to secure heavy loads against shifting
- Marine mooring and anchoring where adjustable tension is needed on wire rope or synthetic lines
- Construction rigging for temporary guy wires or stabilizing structures during erection
- Towing and recovery operations using turnbuckles to tension winch lines or bracing cables
- Industrial equipment installation where alignment and tension control are critical

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 eye and hook ends | The jaw-jaw version allows direct connection to other jawed components, reducing the need for intermediate shackles and simplifying setup |
| Turnbuckle with hook and hook ends | Jaw ends provide a more secure and stable connection to flat or structural surfaces than hook ends |
| Turnbuckle with screw pin | Jaw ends eliminate the need for a pin and cotter, reducing the number of parts and potential failure points |
| Non-galvanized turnbuckle | Hot-dipped galvanizing extends service life in outdoor and marine environments where corrosion is a concern |
Use Guide
How To Use And Inspect Crosby HG 228
- Match the stamped working load limit to the actual line load, not the equipment rating
- Ensure both jaw ends are fully engaged with the connected component to prevent slippage
- Inspect the turnbuckle before each use for deformation, thread damage, or finish wear
- Do not exceed the maximum take-up length specified for the size to avoid overloading
- Keep the turnbuckle aligned with the load path to avoid side loading and bending stress
- Retire the turnbuckle if the body shows permanent deformation, the jaw is cracked, or the marking is unreadable

Answers
Crosby HG 228 FAQ
What does jaw-jaw mean on a turnbuckle?
It means both ends of the turnbuckle have jaw-shaped openings, allowing direct connection to other jawed components like hooks, shackles, or structural points without additional fittings.
Is this turnbuckle rated for overhead lifting?
Yes. It is drop-forged with a 5:1 design factor and suitable for overhead lifting when the working load limit is not exceeded and proper installation is followed.
What safety factor does this turnbuckle have?
A standard 5:1 design factor, so the minimum breaking load is five times the stated working load limit. Proof load testing and breaking strength validation are performed on each batch.
What certificates come with the order?
A Material Test Certificate to EN 10204 3.1 is supplied with every order. Each batch undergoes proof load testing and dimensional inspection.
Can you custom stamp our brand and tonnage?
Yes. Custom tonnage stamping, private label marking, and OEM packaging are standard options. The finish can be galvanized, powder coated, or electrophoretic black.
How are they packed for export?
Packed in cartons or gunny bags, then palletized. We can configure the carton count and pallet pattern to match your warehouse or retail requirements. Free storage in Qingdao for two months is available.
What sizes and capacities are available?
Sizes range from 1/4”×4” to 2-3/4”×24”. Working load limits range from 400 lbs to 34,000 lbs. Full dimensions and weights are listed in the product table.
