Personal Gear Guru – Bob M.

This question was sent to me via our free Personal Gear Guru service by Bob M., asking about rigging both a speedlight and a studio strobe to the 40″ Grip Arm of a 40″ Master C-Stand Kit. 


I’m new to this so here is my question:

All I need to make a 40″ master c stand kit work with a speedlight or studio strobe would be a “5” baby pin”?

Any videos/webinars on using c stands and speed lights?



Hey Bob,
For mounting a studio strobe with a standard baby (5/8″) receiver, yes all you would need is a 5″ Baby Grip Pin 
For mounting your off-camera flash to the 5″ Grip Pin, you will need two more adapters.
First you will need a a 5/8″ (16mm) Receiver with 1/4″-20 Thread
The second adapter you’ll need is a Hot Shoe Adapter to mount the speed light to the 5/8″ Receiver with 1/4″-20 Thread
As an alternative to the 5/8″ Receiver with 1/4″-20 Thread, you can use the Tilting Umbrella Adapter with the Hot Shoe Adapter to mount your speed light to the 5″ Grip Pin and this also gives you the ability to mount an umbrella to give you a large soft light source. 
As far as videos/webinars are concerned, we have a couple for you. 
This is the 5″ Grip Pin Video which shows using the combination listed above.

I hope this answered your questions. Please let me know if I can help you any further.

This question was sent to me via our free Personal Gear Guru service by Randolph, asking about our 5″ Grip Pin to mount a lighting fixture in the 40″ Grip Arm that comes with a C Stand Kit.


First I’d like to say thank you for all the wonderful videos you have on this site. They’re very informative and easy to follow.
I was going to buy the Avenger A2030D 9.8′ Turtle Base kit + Avenger E650 Baby (5/8″) Pin with Collar to use with a beauty dish.
Instead of the Avenger stand, I would like to buy the Kupo 40″ Master C Stand with Turtle Base Kit. Is the Kupo Baby 5/8″ (16mm) Snap-in Pin the pin I’ll need to purchase?



Hey Randolph,

You will need the 5″ Grip Arm Pin to support your lighting fixture. Just place it in the baby (5/8″) opening in the grip head, position the pin angle, tighten the grip head, and you’re ready to rock!

Remember to place one of the legs in-line with the grip arm so it won’t tip and to use a sandbag on the turtle base for safety! If you have any other questions, feel free to ask!

Thank you for the inquiry, your comments on our videos and for supporting Kupo Grip!

Hex Grip Head

The Hex Grip Head is identical to the 2-1/2” Grip Head with Big Handle – Black (KG203111) but instead of being mounted to a baby 5/8″ (16 mm) receiver, it’s mounted to a hexagonal stud designed exclusively to fit the Convi Clamp or Super Viser System. The ability to mount a grip arm to one of these incredibly versatile clamps gives you the ultimate flexibility in rigging possibilities. You can mount a modifier such as a scrim or silk on the same stand that the light fixture is mounted to.

40″ Hex Grip Arm with Big Handle


Have you ever tried to use a grip arm as a mini boom by mounting a light fixture at the end of it, only to find gravity pulling it downwards because the set screw wasn’t strong to hold up its weight? We’ll now there’s a simple solution.

Kupo just introduced an exciting innovation in grip arm design. At the end of our 40″ grip arm, you will find a baby hex pin with six milled flat surfaces. So now you can mount your light fixtures or accessories on the end of your grip arm like a mini boom and they won’t rotate due to the set-screw of that fixture or accessory, locking onto one of the sides of the hex pin.
