Kupo KCP-359-9in Steel Spring A Clamp

$20.00 /day

Premium jumbo industrial-grade 9-inch ( $225\text{mm}$ ) steel spring A-clamp, engineered by industry-standard Kupo, now available for rental in Hong Kong. Features an ultra-deep frame footprint with an intense high-tension steel coil to lock thick structural wood boards, heavy polystyrene backgrounds, or wide studio scaffolding columns firmly with zero marks. (Note: This rental package covers spring clamps only; stands and backdrops 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-359 9in Steel Spring A-Clamp —universally recognized on commercial film sets and major studio stages as the Jumbo 9″ Spring Clamp or Extra-Large A-Clamp—is the ultimate heavy-duty rigging utility designed for professional gaffers, key grips, and production teams, making it a powerful asset for equipment hire in Hong Kong. Engineered specifically to provide maximum structural jaw clearance and extreme clamping pressure where standard 4-inch or 6-inch clips fail to wrap around thick profiles, this massive nickel-plated steel clamp pair handles the most demanding studio rigging parameters with ease.

When executing an equipment hire for complex commercial set builds, multi-layered background drapes, or heavy-duty outdoor video projects in Hong Kong, maintaining structural safety under massive load shifting is non-negotiable. The KCP-359 sets itself apart with its extra-deep mechanical jaw reach, finished with thick, non-slip protective PVC rubber coated tips on both the jaws and handles. These protective jackets allow staging crews to tightly secure heavy seamless backdrop setups, thick polystyrene foam insulation cores, or oversized fabric drapes onto thick crossbars and structural beams without experiencing surface tearing, sliding, or permanent metallic scratch marks.

Applicable Scenarios:

Securing Heavy Backdrop Material and Canvas Folds: Clamps massive canvas backgrounds, heavy theatrical drapes, or muslin drops cleanly onto thick support bars inside production spaces in Kwun Tong or Chai Wan, keeping materials perfectly taut.
Locking Jumbo Polyboards and Studio Flats: Clips extra-thick, multi-inch polystyrene bounce boards or large acoustic panel screens securely onto vertical rolling combo stands or heavy-duty autole poles.
Rigging Large Diffusion Frames on Location: Secures heavy-duty overhead diffusion screens, flags, or wind-breakers onto scaffolding grids or industrial steel frames during location shoots in Central.

Jumbo Heavy-Duty Mechanical Footprint: Massive 9-inch ( $225\text{mm}$ ) total frame length provides an expanded maximum jaw opening width of approximately 85mm, ideal for gripping deep tables and thick structural pipes.
Industrial-Grade Internal Coil Spring: Ultra-high-strength steel spring delivers immense, uniform torque pressure that naturally resists material shifting or sliding under high vertical load paths.
Non-Slip Protective Rubber Coated Tips: Jaws and handle tips are encased in heavy-duty black PVC rubber jackets to protect delicate surfaces, backdrops, and hands from mechanical scraping.
Rugged Nickel-Plated Steel Construction: High-tensile cold-rolled steel composition handles extreme physical stress, completely resisting rust, corrosion, and harsh on-set impacts.
Extended High-Leverage Squeeze Handles: Elongated handle profiles allow assistant crews to squeeze and apply intense mechanical clamping pressure safely with minimal physical hand fatigue.

Kupo KCP-359 9″ Steel Spring A-Clamp x 1
(Note: This rental listing covers the standalone jumbo spring clamps only. C-Stands, background crossbars, heavy canvas backdrops, and rolling combo stands are available for add-on rent separately at our Hong Kong studio.)

Q: Are the vertical light stands, rolling combo stands, or background crossbars included inside this rental package?
A: No, they are not. This specific rental listing covers two standalone Kupo KCP-359 9-inch steel spring clamps only. It is intended for production teams who already have their own support gear or wish to build a custom kit layout. If you require a complete support system, please remember to add matching C-Stands or backdrop crossbars to your Hong Kong gear allocation.
Q: What is the main structural difference between this KCP-359 clamp and the smaller KCP-356 or KCP-354 clamps?
A: The KCP-354 is a standard 4-inch clamp for small gels, and the KCP-356 is a 6-inch clamp with a 75mm opening. This Kupo KCP-359 is a jumbo 9-inch clamp featuring an exponentially stronger internal spring coil and a massive jaw opening of up to 85mm with an extra-deep structural neck. It is designed specifically to reach past edge frames and clamp onto deep profiles like heavy wood beams, thick canvas folds, or industrial scaffolding tubes where smaller clamps cannot reach or fit.
Q: Can these steel spring clamps withstand the heat of high-power continuous lighting fixtures?
A: The clamp skeleton is made of rugged nickel-plated steel which handles high thermal limits perfectly. However, the protective black tips are made of PVC rubber. When clipping large flags or diffusers near high-power continuous lights, ensure the rubber tips are positioned away from direct contact with the hottest parts of the metal housing to prevent the protective jackets from melting.
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.
