3′ Builder® Rig Height Extension

Need some extra headroom for ring muscle-ups? Use the 3′ Builder® Rig Height Extension to convert a 9′ Builder® upright into a 12′ upright, or 12′ upright into a 15′ upright. Each extension tube comes with 4x straight brackets. Only compatible with Get RX’d 3″ x 3″ Builder® rig uprights.
