Help with xpole mount

Hi all, I sent a message to xpole customer support some days ago and haven't heard back :( I'm moving my pole to the garage and want to install it with a permanent mount. Garages, being part of the outside of the house, have a slight elevation so I was thinking that the vaulted ceilings mount would be what I needed but, can the angle be adjusted? The angle would be minimal but it's still not perfectly straight so I would imagine the regular permanent mount wouldn't work. Does anyone know the answer??! Thank you in advance 🙏
