An automatic boom barrier: a support post with a control housing and a hinged yellow-and-black striped arm, modelled as vehicle access control equipment. Use it at car park entrances, residential compound gates, service yards and parking scenes, where it reads instantly as a checkpoint. The arm can be posed up or down depending on the scene. FBX, OBJ and USD source files are included (GLTF, GLB and USDZ are auto-converted by Fab). Please note: ground surface in the preview renders is for display only.
