Brief Description: Fabricate/Install SL40 Support Angles in Sub Panel
I decided to add some support to the cutout for the SL40 Comm tray in the sub panel by cutting a couple of 3/4 x 3/4 angles and drilling and riveting them to the sub panel. This not only stiffens the sub panel but it also provides great support for the trays, especially now that they are all joined together with the two side straps.
