Another Rex Tool Modification – By: Andrew Brassard

Ever since my first blog on modifying a standard rex tool to be able to carry it in your pocket I have received lots of emails and had lots of questions about which modification (the pipe or the adz bracket). The reason why there is a debate about which one is better or more applicable is because I tend to like the adz bracket modification better because it allows you to rock the tool side to side and "walk" tough cylinders out off the door, with the pipe modification you loose the ability for the side to side movement.

The main reason that some guys like the pipe modification better is because in their company they utilise the wide adz halligan. So my latest project was to come up with a way to use either the pike or the adz to pull the cylinders. I have also seen on different blogs and websites  several other modifications by other people to give the ability to use both, this was usually accomplished by welding a pipe on the top of the adz bracket. This modification made the tool extremely heavy and awkward. Remember that this is a tool that you want to carry in your pocket most of the time, it should not look like something that a gas station should have the rest room keys attached to!

The first thing I did was cut the handle off a standard Rex Tool with a band saw. The next thing was I cut the length of the head down by 1'' to decrease the weight and size of lock puller, the head was now ready for the new staple. The new staple had to be made to accommodate the pike and the adz, the answer was far simpler than you might think. With the help of Jamie Hiller at H and R Machine I used a shop press to bow the centre of a piece of 1/4'' plate, the ends were then bent to fit the width of the lock puller. A MIG welder was then used to attach the bracket to the lock puller.

This modification gives you the best of both worlds, it allows you to be able to perform through the lock using either the pike or the adz. This new modification gives you a tremendous and light weight lock pulling option that you can keep in your pocket.

    Do you ( all the brotherhood instructors) prefer using a lil’ Rex over the Rex tool?

    Very creative thinking. Keep it up!

    I am looking to have this mod done. The first thing I need to do is purchase a Rex Tool. Do you recommend getting the original Rex and cut the handle of as you have done here or buy the Lil Rex and try to modify that version?
    Thanks bro,

We specialize in the basic fundamentals of firefighting. While we believe that hazardous materials, terrorism, emergency medical and the various rescue disciplines are essential parts of the Fire Service, we also think that the basic fundamentals of firefighting have been overlooked in recent years. We are here to help turn that trend in the other direction.
