Kupo KCP-720B-Double Convi Clamp (Black)

$40.00 /day

The definitive industrial-grade Kupo KCP-720B matte black Double Convi Clamp (Double Super Clamp), engineered from two rugged die-cast aluminum clamps permanently locked at a rigid 90-degree physical layout, now available for rental in Hong Kong. Built to bridge, interlock, or extend vertical stand columns, backdrop crossbars, and heavy studio piping with maximum mechanical safety. (Note: This rental package covers the double clamp assembly only; stands and extension rods are available separately.)

A 10% damage waiver fee will be applied to your order in the rental basket unless proof of own insurance can be supplied.

The Kupo KCP-720B-Double Convi Clamp (Black)—universally referred to across professional film, television, and commercial sets as the Double Super Clamp or Fixed 90-Degree Pipe Coupler—is a core structural rigging component designed for key grips, studio gaffers, and creative production crews, making it an indispensable asset for equipment hire in Hong Kong. Engineered by permanently riveting two high-capacity Convi clamps back-to-back at a strict, unyielding 90-degree axis line, this heavy-duty mechanical tool provides an absolute physical link for structural pipe configurations where individual loose components might twist or buckle under load.

When executing an equipment hire for complex commercial background builds, multi-layered overhead truss arrays, or fast-paced location sets in Hong Kong, maximizing rigging rigidity without multiplying bulky stands is a critical safety parameter. The KCP-720B excels in these setups by allowing crews to interlock two separate cylindrical bars, speed rails, or stand tubes ranging from 5mm up to 51mm in diameter. Equipped with dual ergonomic metal T-handles and removable plastic wedge inserts, it locks flat or round architectural paths down into a single, non-slip structural framework with zero loose play.

Applicable Scenarios:

Rigidly Linking Crossbars to C-Stands: Mounts cleanly onto the vertical riser tube of a heavy light stand inside production spaces in Kwun Tong or Chai Wan to extend a rock-solid horizontal background pipe or boom arm.
Building Right-Angle Studio Frameworks: Connects two independent scaffolding pipes or speed rails together at a clean 90-degree axis to construct customized overhead support grids or green screen frames.
Low-Profile Multi-Stand Stabilization: Bridges two nearby vertical columns together on location in Central to create a reinforced structural line capable of supporting heavy client monitors or multi-light arrays safely.

Rigid Fixed 90-Degree Axis Geometry: Back-to-back dual clamp configuration is permanently welded and riveted, completely eliminating loose mechanical play or drifting between intersecting lines.
Dual Multi-Surface Clamping Performance: Both clamp jaws accept round tubes and columns from 5mm to 51mm, with two removable plastic wedge inserts included for non-slip flat surface biting.
Heavy-Duty Die-Cast Aluminum Build: High-strength structural alloy composition easily manages severe mechanical torque parameters, supporting heavy vertical payloads safely.
Stealth Matte Black Hardened Finish: Black powder-coated anodized treatment minimizes specular glares and unwanted metallic reflections under high-intensity continuous light streams.
Dual Independent 16mm Hex Sockets: Both sides retain the standard 5/8-inch receiver sleeve with spring-loaded safety push buttons, allowing crews to snap extra baby studs or accessories directly into the spine structure.

Kupo KCP-720B Double Convi Clamp Assembly (Black) x 1
(Note: This rental listing covers the standalone double clamp tool only. Scaffolding pipes, telescopic crossbars, C-Stands, baby pins, and lighting fixtures are available for add-on rent separately at our Hong Kong studio.)

Q: Are the vertical light stands, scaffolding pipes, or horizontal crossbars included inside this rental package?
A: No, they are not. This specific rental listing covers the standalone Kupo KCP-720B double clamp only. It is intended for production teams who already have their own bars on set or wish to configure a custom scaffolding kit. If you require a complete operational backdrop or overhead bar structure, please remember to add matching telescopic crossbars and heavy steel stands to your Hong Kong gear allocation.
Q: Can the two clamps be rotated independently to change the connection angle?
A: No, they cannot. This specific KCP-720B model is a fixed right-angle double clamp, meaning the two jaws are permanently cast and joined back-to-back at a rigid 90-degree angle. It is built specifically for structural integrity where you need to guarantee that a horizontal pipe remains perfectly perpendicular to a vertical stand column without any rotational slipping. If you require infinite angle articulation, please search for our swivel double clamp variations.
Q: What is the purpose of the small plastic wedge inserts found inside the jaws?
A: The two removable plastic wedge inserts are used when you need to clamp either side of the tool onto flat surfaces like table lips, doors, square timber wood beams, or flat plates. When you are clamping onto standard round pipes or light stand columns, you simply slide the wedge inserts out so the jaw’s native curved profile can wrap perfectly and securely around the cylinder.
Q: How is the rental fee calculated?
A: The rental fee is calculated on a 24-hour basis per rental period at Dream Scenes Studio Hong Kong.
Q: Is a deposit required?
A: Yes, a corresponding deposit is required for all equipment rentals in HK.
Q: What payment methods are accepted for the deposit?
A: We accept credit card authorization for the deposit, which is fast and convenient for local and international crews.
