Wedge 16 x 4 Triple Curved

The Ultimate Streamliner

The Wedge 16 x 4 Triple Curved (45301) is one of the most distinctive large-scale elements in the LEGO® inventory. Spanning a massive 16 studs in length, this part features a complex "triple curved" surface that tapers smoothly, making it ideal for creating long, aerodynamic shapes without the blockiness of standard bricks. It is primarily used as the top fuselage section for passenger jets or the sleek hull plating of spacecraft.

Aviation and Space Essentials

This part is a staple for anyone building modern transportation. In LEGO® City sets, it frequently forms the roof and nose sections of cargo planes and airliners. For sci-fi enthusiasts, it is a critical component for the smooth, armored exteriors of Star Wars cruisers and custom spaceships, providing a professional, stud-less finish that looks aerodynamic and fast.

Versatile Geometry

Beyond aircraft, the 16x4 curved wedge is excellent for high-speed trains and futuristic architecture. Its hollow underside allows for interior cabin space or structural reinforcement. Because of its unique geometry, it often serves as the defining "shell" piece that dictates the scale and curvature of an entire model.
