Fourtitude Single Tank Mounting Trays 20oz

Makes mounting a single fuel tank or smoke tank much easier and stronger than with velcro straps alone. This tray design captures the neck of the tank for an exceptionally strong mounting solution. Works really well in warbirds and narrow fuselages where the installation is difficult to access. The tray is CNC cut from .125” (3mm) thick Birch plywood that assembles in minutes.
