[TowerTalk] Cadweld

[Kirk]

I am interested in purchasing several Cadweld One-shots from RF Connection.
I sent them an email requesting information but received an “out of office”
reply.  They won’t be back until the middle of July.  Being an impatient
individual I wonder if you would know the answer.  

What is the difference between the following Cadweld order numbers?  I’m
using #4 copper to ¾ ground rod and know I would be using GR1-181V, GT1-181L
or NT1-181L but have no idea as to the difference between these numbers.

 

Thanks,
