Slope 33 3 x 6 without Inner Walls 58181

The LEGO® Slope 33° 3 x 6 (58181) provides a broad angled surface for creating smooth roof sections, sloping panels and streamlined LEGO® structures. Its 3 x 6 footprint makes it especially useful where a larger sloped element is needed instead of several smaller bricks.

This version features an open underside without inner walls, distinguishing it from the similar LEGO® slope 3939. The difference in internal construction is particularly important when selecting a matching replacement for an existing model or working with specific connection arrangements.
