Installation Resources
We recommend the included Mount Screws be torqued to 15 in-lb using an appropriate tool.
The screws require the installer to use a Torx T-10 driver. We strongly recommend the use of a Torque Limiter, like the Fit-It-Stick preset for 15 in-lb. The above mentioned tools are NOT included with the mount.
Remember, when buying tools, you get what you pay for.
