Buckingham Buck Rigger Double Sheave block

The advantage of the BuckRigger™ block from Buckingham is the swiveling side plate, which enables quick and easy rope installation without removing the block from the attachment point.

When configured with optional sheaves, the OX BLOCK™ can be used to create a 4:1, 5:1, or 6:1 mechanical advantage that reduces the amount of force required to lift heavy loads. The double sheave with a swiveling eye has a 1.5" (38 mm) rope capacity and a WLL of 2000 lbf. 

36 kN - 8000 MBS.
