These seem to be the perfect combination of top/bottom parallel clamping
and using cauls.
They use shop made cauls as part of the clamping mechanism, so you get
flatness and it prevents boards from popping up at the seems under
compression.

I've been waiting for these to go on sale and will probably get at least
four.
Seems like a no-brainer considering the great design and how much
cheaper they are than good parallel clamps.

I go in with caution because having bought many of Rockler's
"inventions" and being greatly underwhelmed due to low quality control
and under-performance, I've grown to be wary of their house brand.

However I'm fairly certain, they didn't invent, nor manufacturer these.
We'll see how it goes.

Anyone have these, already?



I would caution you to wax the cauls so that they do not stick to the
panel joints.

So how come when I posted a link to a set up that used cauls you
chastised me...errr...I mean...politely stated:

"IMHO learning to glue up panels correctly negates the need for cauls
of any kind."
