Device for warning or barrier gate
A device for a warning or barrier gate and methods that use the device can include a first arm section that includes a tenon and an arrangement of apertures through the tenon, and a second arm section that includes a mortise and an arrangement of apertures through the mortise. The apertures can align, and fasten together, to form at least part of an arm assembly for the warning or barrier gate. Manufacture of the device can occur in the field during installation of the warning or barrier gate. The device can be reciprocated 180 degrees from a closed position perpendicular to a roadway to an open position that rests parallel to the roadway.
