Safety Engineered Hoist Rings - Inch

HOIST RING MATERIAL: Alloy steel (Certified heat treatment). Black Oxide . SAFETY FACTOR: 5:1

RANGE OF MOVEMENT: 360° Swivel, 180° Pivot

INSTALLATION: Tap work piece for hoist ring screw with axis vertical to mounting surface. Work surface should be flat and smooth to provide full 360° flush seating for the bushing flange. (SAFETY NOTE: Some loosening may develop after prolonged service in a permanent installation. It is advisable to periodically re-tighten the mounting screw to maintain the specified torque value.) The use of free fit spacers between the bushing flange and mounting surface is not recommended as this will reduce the safe load rating on angularly applied loads. Hoist Ring must be free to swivel 360° and pivot 180° at all times.
