That's pretty sharp right there man. I WAS gonna mount somethinng like that on mine to hold the Terrova BUT when I installed it, I noticed just how close to my Add-a-seats it was. HUMMM, got me to thinking, yeh, scarey I know. I have a 2 foot long, 3/4 inch thick Bungee cord and I wrapped it TIGHT around the add a seat bars. Suckers secure as all get out.
