Swivel Hoist Rings
They are a great alternative to eye bolts and they maintain their full capacity when pulling or lifting at angles. They also have a 360 degree rotation and 180 degree pivot.
Hoist rings come in "engineered" style handles or forged style handles in various sizes and capacities. It is again important to use only brand name products which shows the manufacturers name or logo and that they have installation and application information readily available for you to read and understand.
When eye bolts cant meet the work load limits you require, than swivel hoist rings are an excellent alternative.
