This cube-shaped adapter has two slots. Arranged at an angle to each other, they allow an additional device that has a quick-release foot to be attached horizontally or vertically. The underside of the FA-04 has a round recess with a diameter of 16 mm, provided with a safety clamp and rotary knob. All Leofoto accessories that have a 16 mm thick fastening button can be inserted here. For example, this is the case with the PC-90II smartphone holder from Leofoto. The FA-04 hot shoe double adapter is made of CNC-milled aircraft aluminum, weighs 34 g and is only 28 x 28 x 23 mm in size.
