Inspired by a post on DIY Photography, I spent $1.14 and made a flash bracket capable of holding up to four speedlights. The base piece is an electrical box, found at any hardware store — they’ll all vary in configurations; I chose one that had pre-drilled holes in the back for easy attachment to my light stand.

Parts Needed:

* electrical box ($1 to $2)

Already had on hand:

* fender washers
* wing nut
* winged screws (or any screws with 1/4″-20 thread)


* light stand, tripod, or other support
* something that will hold each flash (could be cold shoes, umbrella swivels, or radio triggers — anything with 1/4″-20 female threads on bottom)
* flashes, of course, and a way to trigger them off-camera

Tools needed:

* None

These electrical boxes come with pre-punched circles — mine were 7/8″ in diameter — that you can press out with your thumb. I left the ones in the back of the box; I didn’t need them out. The others, just wiggle them back and forth a few times; they’ll snap off. Discard the circular pieces of metal (I couldn’t think of anything to use them for.)

The pre-drilled holes in the bottom of my electrical box were a perfect fit for the 1/4″-20 thread on top of my light stand, so I simply used a wing nut to attach the whole box. If using a tripod with a 3/8″-16 thread, or some other support method, you could always punch out one of the larger discs on back of the box.

Then it’s a simple matter of attaching your gear. My Cactus V4 wireless flash receivers have 1/4″-20 female threads on bottom, as does the optical slave unit for my ProMaster 5550DX flash. For my two main flashes (LumoPro LP160 and Yongnuo YN560-II), I used the umbrella swivels I recently received for Christmas, which have the same threads in the brass studs. You could also use a simple cold shoe (example)

I mounted one V4 trigger, two umbrella swivels, and the ProMaster flash, using two winged screws and two socket head cap screws. Because of the huge holes knocked out of the electrical box, I inserted washers between the screw and box on the inside and between the box and gear on the outside.

* The Cactus V4 receiver is so light, it could hang by the cable it’s attached to in the images above, so another flash or accessory could occupy its spot.

* This box is solid and sturdy. When you’re selecting one from the store, don’t buy one if it feels thin or flimsy; you’ll be mounting expensive gear to it. With the one pictured above, I’m 100% confident that my gear is safe and secured.

* The umbrella swivels shown here aren’t the ideal solution; they’re really too big for something like this, though they do give you more flexibility in pointing the flash at something (or actually holding an umbrella). I’d rather use cold shoes, but didn’t own any when I did this project.

* All the screws and washers used in these projects have photography-standard 1/4″-20 threads and thus are interchangeable with any other such DIY project. That’s why I didn’t add them into the cost of this one; I already owned them from other brackets. I have a plastic bowl full of various 1/4″-20 threaded screws, wing nuts, and knobs.
