In short
Trimless linear can form L-shapes, rectangles and continuous perimeters, and lit corners like Lopen's keep the light unbroken at every turn.

Lines become architecture when they turn corners.
Shapes
- L-shapes around desks and walls
- Rectangles that frame rooms or tables
- Perimeter lines around ceilings
- Custom geometry
Lit corners
Lopen offers lit corner sections, so light flows around the corner with no dark gap.
Setting out
Shapes need precise dimensions from the reflected ceiling plan and square framing.
