With the two-way bayonet on the back, the F22 and F38 quick-release plate is compatible with both F38 and F22 series products. Additionally, it features a 1/4 screw that can convert the 1/4 threaded hole into a bayonet for the F22 or F38 series, thereby combining the compatibility of F22, F38, and Arca-swiss. The 18-mm NATO clamp is designed for good horizontal expansion. To prevent scratches, we have developed a non-slip rubber pad that enhances the safety of the equipment.
