Radiorax Strut Installation Kits provide avionic support for panel equipment while providing rigidity and customizability as a retrofit avionic mounting solution for most aircraft. With simplified installation, installers are able to position the nuts in the slot exactly where the mounting tray is to be installed and remain adjustable until tightened. When fully tightened, mounting trays remain rigid and retain strength without the use of any backstraps. This Radiorax canted rail tray mount kit (EDMO# RK1040) is 18-inches in length and designed for Breech Baron and other canted panel retrofit installs.
