The Ulanzi U-PAD III Metal iPad Tripod Mount does fit an iPhone 14 Pro Max but only in landscape. So if you are looking for the same high-quality metal tripod mount for mobile phones, you will need to get the Ulanzi ST-27 Metal Phone Tripod Mount.
I got mine from actioncam shop on Shopee for S$33.90.
The build and feel are similar to the Ulanzi U-PAD III Metal iPad Tripod Mount. Solid and premium in an all-metal aluminum alloy body.
There are three 1/4″ screw holes for the tripod mount, two at the back and one at the bottom.
There are also three cold shoe mounts. On top, one at the bottom, and one at the back.
Ulanzi ST-27 Metal Phone Tripod Mount fits devices of lengths between 6 cm and 9 cm, and the mount can be rotated.
If you are looking for a good quality tripod mount for your mobile phone, I highly recommend the Ulanzi ST-27 Metal Phone Tripod Mount instead of the usual plastic one you find in most selfie sticks. It is a small price to pay for securing your mobile phones properly, considering your phone easily costs 20 times more.
