This pedestal comes with a cutout that matches a 2NIP Base surface mount. Brushed stainless: the rounded corners are mirror-polished and each flat surface is polished with a 180 grit #4 finish. There is an access panel on the backside. Whereas a competing bollard that uses a lightweight 2-piece anchor-bollard design will begin to wobble shortly after the initial installation, this heavy duty stainless steel tower will hold steady regardless of the use and abuse because of its one-piece design (post and base are welded together) and its .25" thick base plate that get secured to the floor. See its “Installation Instructions.” Furthermore, this stanchion has passed our facewind testing protocol which determined it can survive sustained Category 5 hurricane force winds of 157 mph.
