The Boomerang Flash bracket has been around for about 7 years now. It has gone through a number of revisions and current models are BBX and BBGv2. The BBX requires prongs to be inserted into the plate to mount, the BBGv2 doesn't. There are two types of Prongs we have used on the BBX. The older model has thin prongs whereas the newer has shorter thicker prongs. In the picture below you can identify which model you have. When inquiring for the prongs please let us know if you have the BBS or the BBX model.
