Buckingham- Ox Block With Attached 4 Sling And Steel Carabiner

The OX BLOCK™ handline assembly, as a whole, can be used for human rescue. However, DO NOT USE P/N 2406 handline hook [MBS 500lbs] or handline snap [MBS 750 lbs] for human support. All components used for rescue must have a 5000 lb. rating, configured to accept human support. For rigging, ensure the weak link has a 4 to 1 safety factor. 
 
The OX BLOCK™ is a rope snatch block with an integrated friction bar used for:
Hurtman/self-rescue
Lowering 
Raising
Snubbing loads
 
It allows the rigging professional to handle loads with greater control. When lowering loads, tension is transferred from the worker to the OX BLOCK™.
The patented OX BLOCK™ replaces standard handline blocks, parted blocks and various snatch blocks.
Has greater WLLs than blocks of similar size.
When configured with optional pulleys, the OX BLOCK™ can be used to create a 4:1, 5:1 or 6:1 mechanical advantage reducing the amount of force needed to lift heavy loads.
The advantage of the pulleys used by Buckingham is the swivel side plate that allows for quick and easy rope installation without removing the pulley from the connecting device.
