Back in the days when I was doing a lot of troubleshooting in the field I never left home without my Pocket Rocket (that's the name the manufacturer gave it). I used to see a lot of oddball pipe sizes on those older heating systems. I ran into 3-1/2" and 7" pipe and fittings from time to time, but it never threw me because I had my Pocket Rocket. I just pushed this neat little tool up against the pipe until it stopped and then read the pipe size on the scale. Simple is good!

I found it especially helpful on jobs where the pipes were covered with insulation, especially asbestos insulation. You don't want to disturb that stuff! I would carefully cut a slit in the insulation with my Swiss Army knife and slide the Pocket Rocket into the space. When I pulled it back out, I knew exactly what I was dealing with.

Now, I'll admit that I didn't need my Pocket Rocket on every problem job I visited. But I'll tell you this, when I ran up against the hidden pipe or the oddball pipe, NO other tool would have told me what I needed to know (It's also a great way to settle arguments).

The Pocket Rockets we have for you are made from thick anodized (so that the writing won't wear off) aluminum. The two arms are held together with a strong brass grommet. This is truly a professional's tool. You can use it to measure pipes from 1/8" to 16" and when you open the arms all the way, you have a very accurate 14" rule. The Pocket Rocket also has a chart showing the outside diameter of pipe sizes from 1/8" to 16", as well as a chart showing the conversions between fractions and decimals (from 1/32" to 32/32").

If you're not completely satisfied with this most unusual (and cool!) tool, just return it to us for a full refund. But I think you're going to be glad to have it handy. I sure was!
