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?

I have the one with the plastic hex screw inside the center hole.And it has a metal piece that spins when you try to adjust the screw. What's the best way to deal with this type?
You need to close the clamp to adjust it! If you close it the screw won't spin, it will tighten up. Tighten until you start to feel just a little resistance, that should do it!
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,
