The ARINC 791/792 Adjustable Fittings for existing and emerging aerospace applications allow for simple and efficient installation performed using only basic hand tools. They do not require special fixtures or tools, shims or match drilling. They are both ARINC 791/792 and RTCA/DO-160 compliant as well as original equipment manufacturer (OEM) certified. These fittings ensure the lowest possible installation height for electronically steered antenna (ESA) applications, provide z-axis adjustability to account for structure variations, and minimize labor on the line or at the MRO.
