Combine this purchase with other items in our store for discounted shipping. Most marine hardware can be divided into two distinct groups these days. Cheap junk made with little, if any, thought to the impact its production has on the environment or the workers involved - or high quality gear made from materials designed to last, by companies that care. We prefer to carry the latter. Plastic and nylon parts are durable for a while and they satisfy price sensitive shoppers. Their production, however, creates numerous toxins, and eventually enough sunshine or stress will cause them to break. Chrome, nickel, and zinc plating can protect metal surfaces for years, but their initial production, especially in third-world countries can cause devastating harm. Painted parts are effective for a while, but paint production is usually nasty, and as it chips and goes over the side, paint carries its own poisons along. At greenboatstuff.com we choose to carry aluminum, brass, bronze, stainless steel, and occasionally wood hardware. In an imperfect world we know these choices are not entirely without their faults. In our opinion, however, they satisfy our criteria for high quality, long lasting products that do the job well while inflicting minimal, if any, harm. |
