About This Product
This little tool from Oregon Rule Co.

is seriously handy if you work with pipes.

The Pocket Rocket measures outside diameter up to 16 inches, and it's got a conversion chart printed right on it that translates that to nominal interior diameter – so you know exactly what size pipe you're dealing with.

It even converts fractional to decimal measurements, which saves you from doing math in your head.

The swing arm extends into a 14-inch ruler, so it doubles as a straight edge in a pinch.
Made from .

040-inch thick white styrene, it's lightweight but sturdy enough for job site use.

You get three in a pack, which is great for keeping one in the truck, one in the shop, and one as a spare.

Engineers, pipefitters, plumbers, and carpenters all love this thing.
