Can anyone help?

I seem to remember schreiber units had a spacing fitting [pre MFI] but you had to cut them if you scribed the units back,I see yours are adaptable.They worked then so why not in the future.Best of luck.

Thanks fella, absolutely right, the adjustment makes the idea work properly now, shrinkage if scribing, over adjustment if needing shims or even as an off-stand if wanting wider worktop space for granite etc. Thanks for the encouragement.
