Maybe all conelock clamps have this. I don't know. If not maybe it's a partial spring assist or partial conelock. The spring in these clamps don't assist in tightening but aid a little when loosening the clamp.
In any case the clamps require very little pressure. I find just the use of my thumb against the lever is enough for both tightening and releasing the clamps. I really like having only three teeth on top of the clamp, easier to fit between the strings.
Again I'm not saying they are a true spring assisted clamp because you feel more pressure as you turn the lever more to tighten the clamp to the base. Like turning a bolt with a nut on the other end for lack of a better description. That would probably constitute conelock. There is however some spring action when loosening the clamp. Like I said earlier maybe all conelock clamps work this way.
Hope this helps.
Hmm, I would call Silent Partner and ask if this is normal.

It is possible to move the lever further (with some effort required), but it is superfluous since the tightening has been completed via the spring action. When released, the lever springs back to the fully open position. The nut at the bottom secures the bases to the table. These are more robust looking than the bases shown on the SP site.
Does it actually just take a flick of a switch on the bases to tighten them then?
