It clamps 48 to 51 mm tube and creates a controlled offset point for lighting fixtures, giving riggers a longer offset for fixtures that need more clearance from the main pipe while keeping the arm length and Working Load Limit clearly defined.\u003c\/p\u003e  \u003ch3\u003eWhy It Matters\u003c\/h3\u003e  \u003cp\u003eOffsetting a fixture from a truss or pipe should be planned, not improvised with loose parts. This arm coupler gives the crew a fixed welded extension, known clamp range, and a length-specific load rating, so side-arm positions are easier to repeat and document.\u003c\/p\u003e  \u003ch3\u003eKey Features\u003c\/h3\u003e  \u003cul\u003e    \u003cli\u003e750 mm welded arm creates a defined fixture offset from the parent tube\u003c\/li\u003e    \u003cli\u003e37 kg Working Load Limit is matched to the arm length for safer specification\u003c\/li\u003e    \u003cli\u003e48 to 51 mm clamp range fits standard 2\" truss tube and stage pipe\u003c\/li\u003e    \u003cli\u003e48 mm welded aluminum alloy tube gives a rigid side-arm structure\u003c\/li\u003e    \u003cli\u003ePolished finish suits exposed polished hardware and general rental stock\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch3\u003eApplications\u003c\/h3\u003e  \u003cp\u003eUse it for side-arm fixture positions, truss offsets, display lighting, studio grids, theater rigs, and controlled lighting placements where the luminaire must sit away from the main pipe.\u003c\/p\u003e  \u003ch3\u003e Compatibility\u003c\/h3\u003e  \u003cp\u003e Fits 48 to 51 mm tube.
