Take your display beyond the shelf with Cobra Arm™, a modular and swappable wall mount system designed to give you more freedom over how you display your LEGO collection.

Cobra Arm allows you to easily swap between different arm lengths without removing the wall bracket, giving you the flexibility to change or reposition your display over time. The integrated ball joint provides 30° of movement, allowing your set to be positioned at a variety of angles for a more dynamic display.

Each mount includes a ball joint post specifically matched to Lego Icons Douglas DC-3 PAN AM Airliner 11378 to provide an ideal fit and secure connection to the set.


Choose Your Cobra Arm Length

Short — Keeps your set closer to the wall while still allowing slight positioning adjustments.

Long — Provides increased clearance and a wide range of positioning options for more dynamic display angles.

Extended — Provides maximum clearance from the wall for especially large or wide sets and more extreme display positions.
