Which size short adapter do ya use w/the "green" Razorhead?
5/16 or 11/32?
Thanks in advance!

I belive they take the 11/32".

Thats what I thought but in another thread someone posted about the Razorhead, someone stated 5/16.

A 5/16" will set deeper into the ferrule and some folks think this make allignment better.I can't say for sure,I haven't had any problems with the 11/32"

For smaller diameter shafts like 2018's,2016's,1916's or carbons,you could use a 5/16" but for thicker shafts like 2117's,2216's, you will need to use the 11/32" or the insert will not butt up against the shaft.

If you are going to use the bleeder blades, you will need the 11/32" short adapter.
