A swivel eye pulley block gives a diversely mountable fixture with dynamic rotation of the block, which can be used with wire rope (cable), nylon rope or fibrous rope.  
 
It is a perfect option when an application needs slight rotation in picking up a load.  It can be mounted in an existing rod, bolt, shackle or other fastening stationary object. 
 
Swivel eye pulley blocks offer an eye that can slide over existing pipes, bolts and rods, or attach over various fittings, such as a shackle.
