Building with the LEGO® 1x2 Slope (3040)

The narrow 2 x 1 footprint makes this slope ideal for detailed rooflines, compact vehicle bodywork, stepped architecture and fine shaping where larger slope bricks would be too wide. Builders frequently combine this element with plates, tiles, and standard bricks to produce clean angled surfaces while maintaining strong connections throughout a model.
