Louver Set, fits 4" Jalousie Glass Product Code: 39-110

I've installed the 39-110 using a 3/16" pop rivet. Just make sure that you don't pull it with too much force. You want a little play so the Louvers will move freely. A standard 1/8" pop rivet diameter is too narrow. You could use the smaller pop rivets with some washers, but I find the 3/16" diameter works best.
