Hoist Rings—For Lifting

180° Pivot

360° Swivel

Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque wrenches are sold separately.

Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.

Warning: Never use to lift people or items over people.

Machined—Machined hoist rings have a smooth finish to protect slings and hooks from damage and excess wear during lifting.

Black-Oxide Steel—Black-oxide steel hoist rings have mild corrosion resistance.

CE Marked—Hoist rings that are CE marked meet European safety standards.

Swivel-Under-Load Hoist Rings—For Lifting


	180° Pivot	360° Swivel

The ball bearing on these hoist rings makes it easy to rotate your load even after it’s suspended. For unbalanced or heavy loads, the base also swivels to compensate for pitch, roll, and sway. Their lifting ring pivots 180° front to back. Ideal for angular lifting, these hoist rings withstand stresses that bend or break eyebolts.

Install the base of these hoist rings flush to your mounting surface. Use a torque wrench to tighten to the recommended torque stamped on the ring.

Warning: Never use to lift people or items over people.

Eyebolts—For Lifting

Also known as machinery eyebolts.

Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings. Eyebolts without shoulder are for vertical lifting only.

Warning: Never use to lift people or items over people.
