METAL ARM 4” SQUARE POLE MOUNT;INTERNAL TENON ADAPTOR;Black Finish

1. 4″ Square Pole Mount: This likely refers to a metal bracket or arm designed to be attached to a square pole with a 4-inch width.
2. Internal Tenon Adapter: An internal tenon adapter is a component that allows for the attachment of fixtures or equipment with a tenon mount (a projection used for mounting) onto the pole mount. It’s “internal” because it fits within the pole mount rather than being an external attachment.
3. Black Finish: This indicates the color or finish of the metal arm and tenon adapter, which in this case, is black. This finish may provide durability and weather resistance while also offering an aesthetic appeal.

This setup is commonly used for outdoor lighting fixtures, security cameras, signage, or other equipment that needs to be mounted securely on poles, particularly in commercial or industrial settings.
