This multi hollow transom maintains the frame integrity, but there are strength limitations.

	For example when:
	Frame width	= 3100mm
	Transom height	= 1500mm
	Highlight	= 600mm
	The transom rates	= 1504Pa
	If the frame width was reduced to 2600mm the rating would increase to 2200Pa.

Lowlight Transom
This multi hollow transom has been designed to drain water out of the system. You will also notice that this transom is slightly weaker than the highlight transom.
	For example when:
	Frame width	= 3100mm
	Transom height	= 600mm
	Highlight	= 1500mm
	The transom rates	= 1149Pa
	If the frame width was reduced to 2600mm the rating would increase to 1702Pa.
