earth strap on gear box

Need to change the earth strap on gearbox as it's seen better days , now I've got a few earth straps knocking about that are a thick solid copper cable with the correct connections on the end , the cables are a good half inch thick , is there any reason I can't use one of these or does it have to be the flat braided one for some daft reason ?

Thanks

 

Go ahead use it

 

Braided is happier with vibration, a solid one won't last so long before metal fatigue snaps it.

 

^this. A flexi-copper job will be more resistant to vibration.

 

Thanks, will use it for now and pick up a braided one when I get chance
