| p.1 #16 · ARCA-SWISS z1 locking question |
this is one of a few reasons I don't really care for a screw type lock.
Image 1- it has a higher potential for Oops! and I can say w/o issue that this particular situation is most likely responsible for most of the Oops's that have and will occur. with out looking and assuming its aligned in the throat of the clamp one can apply a locking load to the plate w/o it being properly in place for safe use. the potential in the image is obvious and there is little indication unless you are, at minimum, attentive
image 2- with a lever type lock you will never get beyond the 90 deg out position unless it is properly in the throat (not skewed) of the clamp assy.
now of course if its lying on top (not in the throat at all on one side) and you start the locking throw you will notice how really easy it will be to get beyond that 90 deg point. that, hopefully would/should be telling you something. well, at least to some.
the lever has both visual and feel indication.
there is no system made that some determined individual can't muck up.
