This umbrella is made using a single piece pole for extra strength and durability, and has simple, clean classic lines, with the contemporary feel of stainless steel and natural bamboo. Our double pulley and rope system ensures easy raising and lowering of the parasols, even on the largest of models. It incorporates a turned bamboo hub and runner with stainless steel brackets, a bamboo finial, and an elegant, practical hour glass shaped pin made from bamboo and stainless steel. The covers are attached using our own bolt-down stainless steel rib end protector system or alternatively sewn pockets. The ribs and supporting arms are fitted with stainless steel through bolts, making all the parts easily interchangeable.
