The Lastolite TriFlash Bracket allows you to mount up to three portable flashes on a single bracket which can be mounted on a standard brass spigot. An umbrella socket allows the use of a reflective or shoot-through umbrella.
To allow the use of two or three flashes in a lightbox.
Unfortunately, the clearance in the metal shoes is too limited to allow proper operation of my Pentax flashes - causing short circuits and malfunctions.
In other words: I cannot use it for what I bought it for.
Can I attach 3 pocketwizard FlexTT5 units with their sppedlights to this bracket?
I mean does it fit?
I've attached two with no problem. I don't own three of them but I would imagine you would need to use the extra shoe mount that comes with the FlexTT5 on the bottom of the flex to give it clearance over the two mounted on the sides.
Hope that helps!
