Set of twelve girder risers for the Industrial Tower System. These risers are used instead of the standard risers. They create a more open look for your towers with cutout truss-style beams.

Each riser measures 67mm between floors, and matches the height and features of our standard riser parts. They feature tab-slots for use with any of our wall parts, and have the right tabs to fit any of our floor kits. Adding these parts to your ITS layout is a great way to add variety and good looks.
