Pretty close fit to our firepit - just a little smaller (1/2") so it will work.  A lot heavier than our old screen.  Be careful when taking the screen off the firepit.  If it is totally closed (as shown on the picture above), the screen will flip open from the centre which may be unexpected.  It can only be safely moved if you flip up the folding screen and then use the hook through both eyes at the same time.
