This SKU refers to the pictured 3' extension arm segment only

Made of lightweight (2lb) non rusting aircraft aluminum

Round foot design slices through material at bottom of pipe and insures accurate invert and pipe diameter measurement

Gives an additional 2ft to work with while measuring pipe inverts and diameters

Measurements are much faster with the Pipe-Mic II because you are measuring with a vertical plumb rod. This accessory slides on and off your grade rod without the need for tools. And by just pulling a pin, you can go from zero to 1-foot vertical clearance under your grade rod!
