Screw the pin into position by hand for quick installation and removal. They're for use in low-vibration applications where the shackle remains stationary. Their flat side allows web slings and straps to lay flat so they don't slide and bunch. Optional spools (not included) fit on the pin to center attachments and keep rope from sliding across the pin.

Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the shackle can lift is significantly reduced.
