Compare the SHAPE C-Stand 40" Stainless Steel Arm and the SHAPE C-Stand Grip Head 2.5" to see which mounting accessory fits your grip setup.
Quick Answer
If you need to reach over a table or flag a light, the SHAPE C-Stand 40" Stainless Steel Arm extends your setup; if you need a secure connection point for lights and modifiers, the SHAPE C-Stand Grip Head 2.5" is the essential adapter.
What Each Accessory Does
The SHAPE C-Stand 40" Stainless Steel Arm is a grip support that mounts onto a C-stand or light stand to hold flags, diffusion, reflectors, or compact fixtures. It gives you horizontal reach so you can position a modifier away from the stand's center column.
The SHAPE C-Stand Grip Head 2.5" is a mounting head that attaches to a C-stand arm or light stand. It provides a 5/8" stand mount and two 3/8-16 threaded holes with set screws, giving you a secure attachment point for lights, flags, and diffusion.
The Trade-Off: Reach vs. Connection
The arm is about reach: it extends your grip point horizontally, which is useful when you need to position a flag or diffuser over a subject or away from the stand. The grip head is about connection: it's the piece that actually holds your accessory to the arm or stand.
In many setups you need both: the arm provides the extension, and the grip head provides the secure clamping point. If you already have a grip head on your stand, adding the arm gives you more positioning flexibility. If you have an arm but no grip head, you can't attach most accessories directly to the arm.
Build and Compatibility
Both accessories are built for professional grip work. The SHAPE C-Stand Grip Head 2.5" features solid aluminum construction and a 5/8" stand mount, which is the standard size for C-stands and most light stands. The two 3/8-16 threaded holes let you attach accessories with standard baby pin or stud adapters.
The SHAPE C-Stand 40" Stainless Steel Arm is designed for the CST40 C-stand, but it also works on other C-stands and light stands with a compatible receiver. Stainless steel construction resists rust and provides rigidity for heavier loads.
Note that the grip head's 2.5" size refers to the width of the head's jaw, not the stand mount. If you're comparing grip heads, this is a standard size that fits most C-stand arms.
Decision Rules: Arm vs. Grip Head
- Buy the Grip Head if...: You need a secure attachment point for lights, flags, or diffusion on a C-stand or light stand. The 2.5" grip head provides a 5/8" stand mount and two 3/8-16 threaded holes for standard accessories. Check that your stand has a 5/8" receiver before purchasing.
- Buy the Arm if...: You need to reach over a table, flag a light, or position a modifier away from the stand's center. The 40" stainless steel arm gives you that horizontal extension. Verify that your C-stand or light stand can accept a 40" arm; the SHAPE CST40 is designed for it.
- Buy Both if...: You're building a versatile grip kit. The arm provides reach, and the grip head provides the connection point. Together they let you position and secure almost any modifier. Consider buying both at once to save on shipping and ensure compatibility.

Best for
- Gaffers and grip assistants who need to flag lights or position diffusion away from the stand.
