About this Product

Solid focus ring for later model Bartech handunit, with diameter 74.7mm. Must produce with "White Strong Flexible Polished" for proper friction fit. 

Requires modification of handunit; need to install a 4-40 socket cap screw as indexing mark for rounded notch. 

This material is porous so you need to finish with a few coats of polyurethane to seal it, but will never be as fully impermeable to markers as rings machined from Delrin or other solid plastic.

IN: 3.165 w x 0.63 d x 3.165 h
