Locates the exact centerline and TDC of any eccentric reducer in seconds. No guessing, no math, no marking errors. Built and field-tested by a working pipeline welder.
The offset between the large end and small end means every layout mark is a guess unless you've got a reliable way to find true center fast.
Get it wrong and your weld prep is off, your TDC reference is off, and you're cutting and re-marking on the clock. This tool removes the guesswork entirely.
One tool covers the full range of eccentric reducer sizes you'll run into in the field.
Set it, mark it, move on. It does the geometry so you don't have to.
Purpose-built for this exact problem — not a repurposed measuring tool.
