Decision points
Why Buyers Specify This Profile
Rounded finish
The 23 mm profile height creates a softer outside-corner geometry.
55 mm legs
Broad legs support a consistent compound transition when correctly installed.
Interior design coordination
Baseboard, opening and square-to-rounded transitions can be planned before order.
Application fit
Where the Product Fits and What Must Be Confirmed
Rounded drywall corners
Creates a softer outside-corner profile than a sharp 90-degree bead.
Residential and hospitality interiors
Useful where a rounded architectural detail is specified for circulation spaces and finished rooms.
Repeated interior details
A consistent profile helps standardize rounded corners across larger fit-out packages when installation templates are controlled.
Selection guidance
Confirm the 23 mm profile height and 55 mm legs against the architectural detail. Coordinate baseboards, trims, openings and any square-to-bullnose transition pieces.
