Adapts to our Invar System

If you use our Invar System as a scale extension tool, you may need the 803-1 V-block kit. These V-blocks work with our Invar System to provide quick access to shafts from 1-1/2" to 48" (38 mm - 1.2 m) in diameter. A spring-loaded steel mounting rod ensures positive contact with the shaft below. The length of the rod is not manufactured to a precision length but is meant for relative "X" or "Y" measurements on rolls. You can see other Invar System Components on this website.

May Be Used With

Brunson Invar System tubes
Any optical tooling scale except 6040 or 6100


Top of mounting rod has internal 3/8"-24 threads, fits Brunson Invar System. Supplied with two Invar system connectors.
