The swing arm umbrella extension fits into one of the accessory tubes on the side of the cart. This will move the umbrella away from the beach cart 32″ while still being attached and secured to the cart. You’ll just slide your umbrella into the end of the arm and into the sand. Get more shade coverage when you add 2, 3 or 4 umbrellas to your setup! You’ll need to stick your umbrella down 6″ into the sand to add stability.
