LEGO® Technic Open Centre Brick Bundle — 32531 / 32324 / 32532, Set of 5

A bundle of five black LEGO® Technic open centre bricks across three sizes: two Technic Brick 4 x 6 Open Center (32531), two Technic Brick 4 x 4 Open Center (32324), and one Technic Brick 6 x 8 Open Center (32532). Each part features a hollow rectangular centre with Technic pin holes running along all four edges, allowing axle and pin connections across the full frame perimeter. All parts are genuine LEGO® elements.

Part Specifications — 32531, 32324 & 32532

All three mould variants share the same open-frame construction: a solid outer border carrying standard studs on the top face and Technic pin holes on the side edges, with a fully open centre void. The 6 x 8 (32532) is the largest in the bundle and provides the widest open span. The two 4 x 6 (32531) and two 4 x 4 (32324) frames offer smaller structural openings suited to compact mechanical assemblies. The combination of sizes in a single bundle supports layered or nested frame construction in MOC builds.
