hi all ive got a 1000x800 mira oblong tray and need a sliding door cubical to fit 1000 sliding door with 800 panel , iv fitted lots in the past but not for a while and have just seen that mira and coram have changed there design the coram one does not have a corner post to attach the 1000x800 panels together ive just spoken to there thechnical department and they say the panels are screwed together (no corner post). looking at the mira cubicals they have an allen key locking system . my question is has anyone fitted these makes/ designs recently and are there any preferences . obviously the easiest to fit is what i want! many thanks
