[RE-wrenches] Attachment Identification

[William Miller]

Friends:

I prefer the EJOTs for this application. JT3 for steel and JA3 for wood. I
prefer the FZD gasket as it fits all profiles. They install in seconds and
require no sealant.

I have had a difficult time sourcing them lately. Anyone know of a reliable
distributor?

Thanks in advance.
