Off the shelf catalog shackles are not individually proof tested. They will carry a serial number on the pin if they were proof tested by the manufacturer. AFAIK any piece of gear that otherwise meets spec could later be proof tested and uniquely numbered, so the process must still be in control. B30.26 requires a proof test to 2 times but no more than 2.2 times rated working load limit for a bow shackle.
Right.....so how many shackles do you see in vehicle recoveries like this? I have seen none.
Proof testing and testing to MBS are different also. A company COULD test a soft shackle to a proof load, I just don't really see the need generally....
Again.....the shackle can be rated to whatever......and then we hook it to stuff with absolutely zero rating for what we are doing and feel 'good' about it.
