The Sub-Ez is a simple cost-effective solution to the common task of installing subs into BHA assemblies on the rig floor or pipe deck.


Safety features:

The Sub-Ez improves safety and efficiency when handling subs into bottom hole assemblies

in the horizontal position. No more slings and shackles required.

 Safety Improvement:

Installing subs into BHA components can be labour-intensive and involves manual handling risks as well as potential pinch points. The Sub-Ez removes the manual handling risks and eliminates pinch points through a hands-off approach that suits modern rig floor operations.

 Efficiency Improvement:

Installing subs into BHA components can take time, depending on the number of components needed. The Sub Ez simplifies the process by making use of existing rig floor winches and allowing offline installation with the use of the crane.

Instructions for use:


  1. Insert the Sub-Ez into selected sub you wish to use.
  2. Using the bell ring and notches in arm centralise the load.
  3. Use handles on the Sub-Ez to easily guide the selected sub into BHA.
  4. Using a chain tong, tighten sub in place.
  5. Lower tugger wire slightly pulling free Sub-Ez
