Number of lids

The minimum size for a lid is 500mm clear opening.
Hinge position
Depending on the number of covers you have chosen, you can determine here how the covers relate to each other. With an even number of covers, the hinge sides can also be opposite each other. This is very useful when bridging large clearances.
