Alternatively, use a shackle that is compatible with the safety chain and a reputable brand. The shackle will have markings to show the brand or enough identification to trace its brand and strength.
Here are more tips for using a shackle:
- Usually the diameter of a shackle pin is larger than the shackle body.
- The strength of a shackle varies according to its grade. An ‘S’ grade shackle is stronger than an ‘M’ grade shackle of the same size.
- Stainless steel shackles are generally unsuitable for trailers, as they have low resistance to bending stresses.
- A bow shackle provides flexibility for more angular movement than a ‘D’ shackle.
