Prismatic jaw for Panavise

[Frank S]

I really like the grooved soft jaws nice touch
I have 2 or 3 sets of the plastic vernier calipers 1 I keep in my electrical bag. If you have ever had to measure the diameter of a cable lug in a 440v panel there are 2 things to keep in mind 1 only 1 hand inside at a time and 2 nothing in your hand that is not insulated very well it is often next to impossible to tell the difference in a 0000 or a 350MCM lug when you can barely see it the same goes for any of the smaller sizes as well but you never risk measuring with a metallic instrument.
