Brick, Round 2 x 2 Dome Top 553

LEGO® Brick, Round 2 x 2 Dome Top is a compact curved building element with a circular 2 x 2 footprint, a central top stud and a smooth rounded profile. MPN 553 is useful where a build needs a small dome, rounded housing or curved finishing detail without the bulk of a larger hemispherical element.

Round Dome Shape and Connections

The part combines a domed upper surface with an open underside designed for standard stud connections. Its raised central stud allows another compatible element to be attached above the dome, while the segmented lower edge creates a distinctive rounded shape around the base.

• Round 2 x 2 footprint
• Curved dome-shaped upper section
• Single central stud on top
• Open underside for standard stud attachment
• Suitable for compact rounded and enclosed details

Building Uses

Use this round dome brick for small roofs, turret details, vehicle housings, engine covers, decorative caps, mechanical forms and compact architectural features. The curved shape also works well in spacecraft, robots, machinery and abstract models where a conventional square brick would look too angular.
