Mitred and butt-jointed concealed boxes turn a corner window into one continuous shading element. Each configuration controls the corner gap, the installation sequence and the way the blind meets the adjacent run.
Each configuration can be sized to your specific opening. See Technical Drawings and BIM files for exact details.
Two cassettes joined at a clean 45° mitre. The gap visible in the ceiling runs continuously around the corner.
One cassette runs full-length and the second butts into its side — faster on site but a small butt joint is visible.
Deeper corner cassettes that accept stacked cellular or very long roller drops in tall corner openings.
Corner-wrapped head boxes plus recessed side channels for a full blackout seal around both walls of the corner.
Concealed blind in a head box paired with a recessed TrackTrim curtain track — shading by day, soft curtain by night.
The questions specifiers and installers ask most often when drawing up corner windows.
