1. BECAUSE THIS GRATE IS DESIGNED TO FIT INTO A DOUBLE SIDED STOVE
EACH OF THE LONG SIDES ARE CONVEX (BOWED OUT)

2. THE DIMENSION ACROSS THE WIDEST PART OF THE BOW IS 263MM (CENTRE)
3. THE DIMENSION ACROSS THE WIDTH IS 420MM (LONGEST LENGTH)
(Note that the short ends are straight and parallel to each other.)
4. THE DIMENSION ACROSS EACH OF THE SHORT ENDS IS 225MM
5. THE THICKNESS OF THE GRATE IS 16MM

ALL THESE DIMENSIONS ARE PLUS OR MINUS 1MM BUT REMEMBER IF YOUR GRATE HAS BEEN USED IT WILL CERTAINLY HAVE DISTORTED BY THE EFFECT OF HEAT FROM THE FIRE AND SO THIS MUST BE TAKEN INTO ACCOUNT WHEN CHECKING DIMENSIONS.
