Pretty sure it's 5/8". Could be wrong. Loren SW Washington

Either 5/8 or 16mm will work. The filter side is 20mm on some and 21mm on others. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
