Pull From Manhole to Manhole in Under 17 Seconds

The lightweight aluminum allows for lightning fast deflection testing. Use our Ripcord Ventilator to pull the gauge through with a parachute in a fraction of the time it takes to pull a gauge out by hand.

Larger Precision Dimensions

Our gauges are accurate within +/- .030 of an inch.

Never Get Stuck With Our Patented TKO

If a gauge gets stuck in a deflection pipe, there's no need to dig it out. Our unique TKO feature removes the stuck gauge with a quick pull on the rope.

Quick Certification

Certify the gauges in the field with accuracy within .030 of an inch, or use our Proving Rings to quickly certify the gauges to required specs.

Custom Sizes Available

We make gauges according to any specification. For smaller size pipe testing we offer a small bullet type gauge. For the larger pipe, we offer a split type gauge which is easy to get into and out of a standard manhole.
