Overview
The 40 Inch C-Stand (short for 40-inch Century Stand) is a heavy-duty, versatile grip tripod type and is considered the standard size on professional film and photo sets. The size designation "40 inches" does not refer to the total height of the stand, but to the length of the riser column – the telescoping section above the legs. This means that when fully extended, the C-stand reaches significantly higher than 40 inches: according to manufacturer specifications, a 40" model reaches a total height of over three meters via the extendable riser sections plus the base.
The C-stand is used in the grip and lighting department to precisely position flags, nets, silks, diffusion frames, reflectors, smaller lights, bounce boards, and set elements in space. The combination of a stable base, grip head, and grip arm makes it one of the most used tools on set.
Construction and Components
- Base (Legs): Three staggered steel legs – one higher, often movable leg (Sliding Leg / "Rocky Mountain" leg) and two lower ones. The staggered arrangement allows for close nesting of multiple stands and setup on uneven ground.
- Riser/Column: Telescoping column section; in the 40" variant, usually designed as a double riser. The length of this section gives it its name.
- Grip Head/Gobo Head: Diamond-shaped clamp for holding 5/8" spigots and accessories.
- Grip Arm/Gobo Arm: Detachable horizontal boom for precise positioning of equipment to the side of the tripod base.
Various base designs are common – such as the spring-loaded base for damping when retracting, and the turtle base, where the riser can be detached from the legs.
Sizes and Classification
Besides the 40" model, the 20" C-stand ("Baby") is the next smaller common size for low setups and tight spaces. The 40" stand offers more height and is suitable for larger lighting and grip setups.
| Size | Riser Length | Typical Use |
|---|
| 20" ("Baby") | 20 inches | Low setups, table setups, tight spaces |
| 40" (Standard) | 40 inches | Standard grip on set, flags, diffusion, smaller lights |
On-Set Use
The 40" C-stand is the workhorse of the grip department: with a grip arm and grip head, cutters, flags, and diffusion frames can be made to float freely in space without the tripod base being in the shot or in the light path. To secure it against tipping, the higher leg is usually rotated under the center of gravity of the load, and the base is weighted with a sandbag. The rule of thumb for tightening grip heads is "righty-tighty" so that the load tightens the clamp rather than loosening it.
