A post base is used to secure a strut assembly to a floor, or other flat surface. Strut bases feature a base and a leg, each containing holes for mounting hardware. The strut beam is secured into the leg of the post base, and the square base is secured to the surface to hold a strut assembly in place. Our 316 Stainless Steel Marine Grade Post Base is suitable for use in salt-water environments, is long lasting and durable. Post base is considered a strut accessory.
