MOUNTING SPECIFICATIONS
Custom Mounting Setups
Planning to mount your RTT using a custom solution? We’re all for it!
We’ll provide a detailed Mounting Spec Guide with all the dimensions and technical info you’ll need to create your own setup.
That said, if you plan to use a custom mounting system, you must select freight delivery at checkout.
We’re not able to perform installs on non-standard GFC mounting setups at our Montana facility due to liability and scheduling constraints.
If you have questions during your install process, feel free to reach out—our team is here to support you
