Quarter Windows

A small percentage of Hardtop customers were concerned with the sailpanel size and potential blindspot.  To address that concern we have an easy to add optional quarter window kit.


  • Improves visibility, eliminates blind-spot 

  • Complete kit, includes gasket

  • Easy add-on to existing hardtops


We recommend trying the top as originally designed, adding the Quarter Windows only if desired later.
