Camcorder Rigs, Cages and Brackets: Fit and Threads

Cage fit, rail standards and thread sizes

A rig starts with the camera cage or baseplate, which is cut for specific camera models, so look for your camera name in the compatibility line. Rods follow two common sizes, 15 mm and 19 mm, and clamps must match the rod diameter. Mounting holes use standard threads: 1/4-20 for most small accessories and 3/8-16 for larger ones. Cheese plates add rows of threaded holes, while NATO rails take quick-release handles and monitor mounts. Mixing standards without adapters leaves parts that do not fit.

Monitor mounts, power and protective cases

Many items here are not rig parts at all: monitor screen protectors and hoods, small batteries, markers and hard cases. Monitor accessories name the monitor models or sizes they fit, such as 5 in and 7 in field monitors, so check the exact model. A rig is a balance of weight, so a heavy cage on a light camera needs a stronger tripod head. Hard cases are often sized for specific recorders and list foam layouts, so check the internal dimensions before choosing.

Questions about Camcorder Rigs, Cages and Brackets: Fit and Threads

Do I need a cage for my camera?

A cage protects the body and adds mounting points for monitors, microphones and handles, so it is worth having when you add accessories. For simple handheld shooting a cage is optional. Make sure it is made for your camera model.

Which is better, 15 mm or 19 mm rods?

Neither is better; they suit different scales. 15 mm rods are common on lightweight camera rigs and shoulder supports, while 19 mm rods are used on heavier studio and cinema setups. Choose one standard and keep clamps and plates to match.

What do 1/4-20 and 3/8-16 mean?

They are thread sizes, given as diameter in inches and threads per inch. 1/4-20 is the standard camera and tripod screw; 3/8-16 is the larger thread used for heavier tripod heads and some rig plates. Adapters convert between them.
