The FPH-H2 phone holder is designed for phone sizes ranging from 56mm up to 86mm, which is big enough to hold an iPhone 15 Pro Max. Equiped with a quick release button, it allows the phone holder to quickly expand without the need to pull making it easier to insert the phone. Additional accessory attachments include a cold shoe and a 1/4” thread. Plus the FPH-H2 can be joined together via the cold shoe in a head-toe configuration allowing it to become a modular unit holing multiple devices.
