Mueller-Kueps Wrench Extender

I bought this 'wrench extender' or 'cheater bar' because the master tech at my job let me use his for breaking loose stubborn jam nuts on inner tie rods. I haven't scraped or banged my elbows on the alignment rack since I started using it, and I consider it the next strongest thing to the oxy-acetylene rig. It's way more secure than the old school method of double-wrenching, and the fact that it can slide up/down the length of the wrench keeps you from being locked into the longest extension if you don't have quite that much space to work. The handle is more ergonomic than even the wrench itself. I haven't had to use the 1/2" drive hole yet, but I can only imagine the kind of torque that would yield! My new ritual is now: 1. pre-soak with PB Blaster for several minutes, 2. select the proper size wrench, 3. lock on the extender. I paid less buying it on Amazon than he did buying from the Snap-on dealer; naturally. I have the larger and smaller models saved on my wish list in case the need arises.
