This tray is made to measure for a perfect fit between the back of the firewall and the back of the instrument panel in all Zenith aircraft. It will work very well on most other aircraft too – you may need to modify it.
Add batteries, solenoids, relays etc to the top of the tray, and you can also use the under-side of the tray to suspend your ECU or other items. Similar things can be done if you purchase a second tray to be used for all of your avionics.
These trays make up the spine for any neat and tidy electrical installation. Please note: One tray is included if you have already purchased the pre-wired engine panel.
