Technic Brick 4 x 4 Open Center 32324

The LEGO® Technic Brick 4 x 4 Open Center (32324) is a versatile structural element designed for rigid frameworks, reinforced assemblies and advanced mechanical models. Its square open-centre design provides space for axles, pins and moving components while helping maintain strength and accurate alignment throughout larger Technic constructions.

Reliable Structural Support for Technic Builds

This Technic brick combines traditional studs with Technic pin holes, making it easy to integrate into both classic brick-built models and complex engineering projects. The open centre reduces weight while allowing components to pass through the middle, making it ideal for frames, supports and mechanical assemblies.
