China LG Supply Kind of High quality Forged Swivels. include G401 Chain Swivel, G402 Regular Swivels, G403 Jaw End Swivels, Jaw End Swivel Shackle, etc.
Rigging swivels like these are very handy for proper load positioning. They help prevent unnecessary twisting and binding of slings and attachments, which in turns helps you get the most out of your rigging.
Keep in mind that some swivels do not have bushings or bearings and they are not intended to swivel under load. (Working Load Limits decrease as slings are twisted, kinked or otherwise fouled).
