i think i still have a set of spot rockers kicking around that you welcome too if i still have them and you want to try them – wont be able to check till later though

are 5 spot and flux rockers the sam length ?

cant link to that
but can comment on your confusion 😆

i think the op is suggesting that the casement is not pulling up to the d/proof strip – not that it has dropped out of square ?

is the hinge set in a channel ? if not can you not unscrew it and reposition it a couple of mm in to close the gap ?
