Panel 1 x 2 x 2 with Side Supports (87552)

The Panel 1 x 2 x 2 with Side Supports (87552) is a favorite among architects and vehicle designers for its space-saving geometry. Unlike solid 2x2 bricks, this element features thin walls and an open back, creating a lightweight structure that maximizes interior space. It is widely recognized as the standard seat back for chairs in trains, buses, and diners, but its utility goes far beyond simple furniture.

Thin Walls for Modular Buildings

In architectural models, this panel is essential for creating partition walls that don't take up too much floor space. It allows builders to construct detailed rooms within LEGO® City sets without the bulk of standard bricks. Its hollow studs on top also provide unique connection points, allowing you to insert bars or decorative elements securely.

Structural Reinforcement

Despite its thin appearance, the side supports make this piece incredibly strong vertically. It is often used to reinforce the corners of containers or crates. When tiled over, it creates a clean, stud-less look perfect for modern designs. It is a staple component in our LEGO® Panel collection for adding detail without weight.
