The Kupo KS-040 28mm Pin W/ M10 Thread & Plate—widely known in the industry as a Junior Pin Flange Adapter—is an essential, high-strength structural rigging utility designed for professional studio gaffers, cinematographers, and production grip crews, making it a highly reliable asset for equipment hire in Hong Kong. Engineered to convert standard threaded gear into heavy-duty stand-ready configurations, this solid steel adapter features a metric male M10 screw on one end, a large anti-twist square metal collar plate in the center, and an industry-standard 28mm ($1-1/8″$) Junior male pin on the other.

When executing an equipment hire for heavy narrative cinema sets, wide commercial studios, or high-output continuous lighting configurations in Hong Kong, preventing heavy fixtures from twisting or loosening under heavy physical torque is paramount. The KS-040 bolts directly through the center attachment point of wide lighting yokes or background bracket frames. The addition of the integrated wide metal flange plate distributes downward pressure over a larger surface area, ensuring a flush lock that eliminates accidental rotational slippage or loose mechanical wobbling when tilting heavy fixtures on heavy-duty combo stands or wind-up columns.

Applicable Scenarios:

• Stabilizing Large Cinema Lights on Combo Stands: Bolts cleanly onto the wide mounting brackets of heavy continuous cinema lights inside deep production stages in Kwun Tong or Chai Wan, keeping the fixture locked solid.

• Rigging Lighting Fixtures onto Scaffolding Clamps: Pairs with heavy-duty structural barrel couplers or truss clamps to hang high-power fixtures safely from overhead pipe grids with zero risk of twisting.

• Heavy Custom Background Support Rigging: Attaches onto custom modular crossbar plates or slider brackets to establish an ultra-stable horizontal layout with robust rolling combo stand infrastructure.
