Hi,recently bought a couple of other manufacturers d sized clamps,not a patch on the precision of the adm item,these have 2 well fitting pins and are sprung,the whole thing feels tight and solid,the back is flush so you can slide a plate across the clamping part,in my case an adaptor plate for the skywatcher guide scope mount,holes line up too.
This is a quality product,i only wish it was in flo's catalogue a while back when i bought ohers,to boot these are cheaper.
