Overview
The KUPO KSD-77 is an empty heavy-duty sand bag for crews who prefer to fill counterweights locally instead of shipping filled bags. Its saddlebag format drapes over stand legs or boom arms, while 1000D Cordura nylon, internal liner bags, triple Velcro closure, and dual haul handles make it a practical reusable weight bag for stage, studio, and location work.
Why It Matters
An empty bag saves shipping weight, but it still has to behave like professional safety gear once filled. KSD-77 is built for that job, with a saddlebag shape that sits naturally over a stand and closures designed to keep sand contained during handling.
Key Features
- Ships empty so rental houses and crews can fill it locally with the preferred ballast material
- Saddlebag shape drapes over stand legs or boom arms for balanced counterweight placement
- 1000D Cordura nylon and internal plastic liners help keep dust in and water out
- Triple Velcro closure reduces leakage when the bag is carried, stacked, or repositioned
- Dual haul handles with a unifying wrap make a filled bag easier to move
Height Range & Reach
KSD-77 is a counterweight accessory rather than a height-adjustable stand, so the useful numbers are size, capacity, and handling weight.
- Bag size: 39 x 46 x 12 cm (15.5 x 18.2 x 4.8")
- Empty weight: 600 g (21.2 oz)
- Working loading weight: 35 kg (77 lb)
- Material: 1000D Cordura nylon with internal liner
- Closure: triple Velcro design
Applications
Use it to stabilize light stands, boom arms, overhead arms, backdrop supports, and temporary production rigs where ballast is required but shipping filled weights is inefficient.
Compatibility
Designed to drape over stand legs and boom arms. Fill material should be chosen by the user and matched to the required counterweight and handling conditions.
