Kupo KSF-25 Shot Bag - 11,5kg

Kupo KSF-25 Shot Bag - 11,5kg (Two-wing design for stable light-stand support)

The Kupo KSF-25 shot bag provides a simple and reliable way to add ballast to stands and grip gear. It uses durable outer fabric combined with a sealed inner filler system to reduce the risk of leaks. The bag’s two-wing shape and fly-away handle make it easy to position over light-stand legs for immediate stability on set.

Durable materials and sealed filler

The bag’s exterior is made from 1000 Denier cordex textured nylon for toughness and abrasion resistance. Inside, a water-resistant polyurethane coating lines the bag to help protect the filler and prevent moisture ingress. 2mm steel balls serve as the internal filler and they are encapsulated inside a poly inner bag that is sealed to avoid leakage.

Design details that aid on-set use

• The two-wing design allows the bag to drape perfectly over light stand legs, giving stable support where you need it.
• A plastic internal liner helps keep dust in and water out, protecting both the filler and surrounding equipment.
• A fly-away handle lets you drape or hang the bag over a light stand leg for quick placement and removal.
• The loading weight is specified on the bag’s blue label for easy identification when selecting the right ballast.
• Made from 1000 Denier cordex textured nylon fabric for a robust outer shell that stands up to regular production use.

Practical use cases

Use the Kupo KSF-25 to stabilise light stands, booms, tripods or similar support equipment during film and photo shoots. Because the bag drapes over legs, you can add ballast without adjusting stand height or position. The sealed filler and internal liner help when working in dusty environments or when you need some protection from light moisture.

FAQ

Question: How does the two-wing design help on set?

Answer: The two-wing shape lets the bag drape neatly over the legs of light stands or tripods, concentrating ballast where it stabilises the support without interfering with stand adjustments or placement.

Question: Will the filler leak over time?

Answer: The 2mm steel balls are encapsulated in a poly inner bag that is sealed. This design prevents the filler from escaping, and the internal liner and polyurethane coating add protection against dust and light moisture.

Question: Can I use this shot bag outdoors or in damp conditions?

Answer: The bag includes a water-resistant polyurethane coating and a plastic internal liner to help keep water out and dust in. These features improve the bag’s suitability for outdoor or variable conditions, though you should always assess the environment and use additional protection if heavy rain or prolonged exposure is expected.

Question: How do I know the bag’s weight without opening it?

Answer: The loading weight is printed on the bag’s blue label, allowing you to identify the correct ballast quickly when preparing gear for a shoot.
