LEGO® Arch 1 x 6 x 2 Thin Top 12939

A wide, low-profile LEGO® arch brick with a thin top design, this 1 x 6 x 2 element (Part 12939) in light cream tone provides smooth curved openings while reducing visual bulk. The extended 6-stud width makes it well-suited for broader spans where a subtle arch is needed without adding extra height.

Structural Shape and Design

The thin upper section combined with the curved underside creates a lighter architectural look compared to standard arches. Its proportions allow for clean integration into longer wall sections, maintaining alignment while introducing curvature across wider openings.

Practical Building Applications

• Wide window frames: Forms elongated arched tops across multi-stud openings
• Bridge elements: Supports shallow curved spans with consistent spacing
• Facade detailing: Adds variation to flat walls without increasing vertical height
• Layered structures: Works within stacked builds to break linear patterns

Explore additional options in the LEGO® arch pieces collection to expand your architectural builds with more curved elements. Part 12939 offers a balanced solution for wider openings that require a lighter visual profile.
