Throughout the world, more people rely on our A Series than all other buoys The A Series is the product that launched the Polyform story. This all-purpose product, with the signature “blue ropehold,” has proven itself in the most adverse conditions. We’ve made a couple of changes to the legendary A-Series for 2001. There’s a new size – the A-7, with more buoyancy than any other buoy in its class, and a redesigned ropehold. The new ropehold has been incorporated into the A-5, A-6, and A-7 and features stronger ribs, a larger eye that accepts a standard shackle, and a new “dual valve” inflation-deflation system. Marking gear in heavy seas is no easy task. That’s why more fishermen use Polyform A Series than all other buoys combined. We’ve seen and heard the testimonials from our customers. You name the ocean, sea, or river, and the A Series has been there. Put your trust in Polyform’s most versatile and well-known product.
