This is a well made coiled PC cord which inserts into the Metz 'standard' SCA 301 adapter, which itself can be used upon any of the SCA-system flashes with their interchangeable adapters.
It stretches to a length that is suitable for just about any application with a flash bracket.
If you simply need a shorter straight cord of minimal mass for use directly upon the camera's flash shoe or with a small bracket requiring a minimal range of motion, select the 36-50 PC Cord instead.
