CWT cable tensiometer

[ZZ]

Does anyone calibrate tensiometers that measure CWT (hundredweight cables)? I've been calibrating tensiometers for 25 years and this is the first time I've ever had a tensiometer in front of me that required them. More specifically CWT-5 to CWT-25 cables. As far as I know they're more common in the UK. I guess next question would be does anyone know of a good supplier here in the US?

I would try your nearest Ship supply warehouse.
