You might try just roughening up the rods with a file or sharp rock or
something; just do the portion where you want the latch to grab.


Hey....good idea. Thanks.

Before you do that take a look at another door where the mechanism works.
Do
your hold-open tabs seem to be facing the right way? The little bent over
portion
of the tab should face the cylinder so that the pressure of the cylinder
against it
causes it to tip a bit and bind. It's a cleverly simple 'pinch' mechanism.
