EYE AND EYE SLINGS
Tapered eyes are automatically furnished on slings over 2 inches wide to provide for a proper relationship between the sling and the lifting hardware.
Eyes with no taper are available.
The bearing points of Half Twist (Type 4) eyes are oriented 90° to the sling body.
The perpendicular relationship between the eye and body in Half Twist,
Type 4 eyes results in a comparatively advantageous choke hitch, when compared to Flat (Type 3) eyes. Half Twist eyes perform equally well in vertical or basket hitches.
