Note: Van's has increased the canopy hinge boss size on later RV-14 models and these will not fit because of the limited space.   The best I can tell, the change occured in 2020 or 2021. 
 
A hinge cover set for the RV14.  You get two hinge covers, 5 nuts (three are spare), one install tool and two screws.  A proven design, installed on many aircraft.   Material is UV resistant.  No painting required unless desired.  If you choose to paint, recommend enamel paint.   See installation guide on the documentation page, link at the top of the home page.
