This is a neck adaptor to attach a Titan Master head to "Asian Kids Day" Protectobot Hotspot or Universe Inferno, for a custom Hosehead application. Note that this panel does not rotate, but instead can only be installed with the neck adaptor facing up.
To remove the original rotating neck panel some cutting is required - recommend just to cut the rotating axle on the left side of the head (opposite the spring). You can leave the spring in place when installling this adaptor.
If you prefer a rotating adaptor - it can be found
here.
