Can I attach 3 pocketwizard FlexTT5 units with their sppedlights to this bracket?
I mean does it fit?
I only have 2-FlexTT5 with 2-SB900 that I use on the TriFlash but a 3rd one will definitely fit to fill all 3 slots. It does become very unwieldy and cumbersome to handle especially if you have to tighten/loosen the locking mechanism on each bracket for any reason when all 3 brackets are filled. I opted to use the locking thumbwheel on the FlexTT5 to secure it firmly on the TriFlash instead.
Also, do not over-loosen any of the 3 individual brackets on the TriFlash!!! Each one contains 2 miniature coil springs that can "pop out" if the locking mechanism is over loosened. It will cause the coil springs to come out of their recessed/aligned positions. I tried to reposition mine carefully after it popped out but I managed to "crimp" the end of the coil spring when re-tightening the locking mechanism of the bracket.
Hope this helps!
