Ultimate Ox Kit – 50061K21


The Ultimate Ox Kit is a complete rigging system that puts numerous rigging options at the user’s fingertips. For example, the user can create a 4-to-1 mechanical advantage on up to a 50’ working height. Similarly, the user can create a 5-to-1 mechanical advantage on up to a 35’ working height.

The Ultimate Ox Kit fits in a small, self-contained bag and can be stored in the back of a truck with ease.

As with most of Buckingham Manufacturing’s products, the UOK is completely customizable. Call customer service to customize or email sales@buckinghammfg.com.

The OX BLOCK™ is a rope snatchblock 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.
  • The Ox Block™ is ASME B30 Compliant.

*Usually ships within 7 to 14 days.
