I ordered a Koger sunshade, which is a fabric shade mounted to metal rods that slide down an aluminum channel. There will be times on our hot-day cross countries that we'd just like to cut down the sun beaming into our beautiful cockpit, and this is the ticket.
Assembly was easy: Mark the canopy centerline, bend the channel to the canopy's contour, affix the channel to the canopy's lower surface with the supplied 3M tape, mount the fabric shades to the rods, and slide the rod/fabric assembly onto the channel.
