Technic Liftarm Thin 1 x 5 with Axle Holes on Ends (Part 11478)

The LEGO® Technic Liftarm Thin 1 x 5 with Axle Holes on Both Ends provides a compact structural element for linkages, frames and moving mechanisms. Part 11478 has a slim half-beam profile, three circular pin holes through the centre and cross-shaped axle openings at each end.

The combination of pin and axle connection points supports several functions within a small footprint. Builders can use the central holes for fixed or pivoting pin connections while the end openings hold axles for rotational assemblies, aligned supports and mechanical linkages.

Its thin profile is useful when a full-width beam would add unnecessary bulk. The straight five-module shape can reinforce compact frames, connect parallel assemblies or create controlled movement between sections of a model.
