This is the plastic "male" portion of the t-top shade fastener, similar to a thumbscrew, which holds the t-top shade to the rubber receiver cups attached to the t-top glass. At this time those reciever cups are no longer available, so you will have to save your existing ones. Give us a call if you have any questions. Note: 2 required per each t-top shade, 4 total per vehicle.
