Jobo Developing Tank Cog Lid

JOBO Developing Tank Cog Lid.

With a separate JOBO Developing Tank Cog Lid, you can keep the original inversion lid that came with your tank instead of converting it with a 1505 cog.

This allows you to use your tank for inversion with the original lid or as a rotary tank with the 1503 cog lid.

Fits all 1500 series tanks.
