Adjusting Sota Reflex Clamp


I have a Sota Reflex Clamp that won't stay in the down position when placed on the record. I know these are adjustable. Does anybody know how to adjust a Reflex Clamp?

Anybody able to tell me what size nut driver I need to tighten the screw?

Thanks,

Hi Robob,

I always use a 4mm Allen Key.
Since I often put the sota on when the platter is rotating, I have to adjust the clamp at times. It works well.

Cheers,
Mario
