To carry the weight of the panels aft (to prevent “pumping” action in a seaway, I replaced the strap tie-downs for the bimini with 1″ stainless support tubes. I put them in the plane defined by the backstays to reduce visual impact. They also appear to provide a way to support the overhanging portion of the aft panel and with no real impediment to tilting the panels when in a marina.
The fight? The set screws provided with the fittings are metric threads but require an SAE Allen wrench and have an SAE diameter. I’m becoming well known in the new hardware store in Deale.
