What is the split height?
Split height is where do you want the two upper panels of your Tier-on-Tier to split up with the lower panels.
By default the system will split halfway from top to bottom, but you can change it depending on your
circumstances, ie. you have a Sash rail, like in the example below.
*Important
The minimum distance from the bottom and the top to position the split height is 300mm (Safety are in
drawing above)
