Wichard Stainless Steel Halyard Shackle > Model No. 11503, 11504, or 11505 > 5/16", 3/8", or 9/16" Max Rope Sizes > High Resistance 17.4 pH S.S. - The Wichard MX is a High Resistance halyard shackle fully forged in 17/4 PH stainless steel to take on the high loads. Product Features: MX has been specifically designed for static load operations and can be used to replace the terminals on flying sail furlers (i.e halyard block) or as a 2:1 purchase for your mainsail. Outstanding strength/weight ratio. Fully forged in High Resistance stainless steel, the MX offers one of the best strength/weight ratios on the market. Compared to standard blocks and for the same line diameter, the MX offers much higher working and breaking loads as well as optimised dimensions and weight. Thanks to its unique design, the MX can excellently distribute the stresses. Its particular shape enables the MX to perfectly position the line to avoid undue and excessive wear on the line. Easy to install. The MX requires no specific lashing knowledge. Its installation is as easy as installing a shackle, thanks to its Wichard self-locking pin. Reliable and maintenance free. The MX does not include any mechanical parts (i.e sheave) which can potentially break. Moreover, it does not require any particular maintenance.

Applications: The MX can effectively replace the terminal of your flying sail furlers, especially the halyard block, by providing an outstanding strength/weight ratio. When luff tension is needed, it can be used: •to replace the halyard block on top swivel •to replace the lower terminal on spool (snap shackle etc.) As a halyard shackle for mainsail halyards (2:1 purchase): The MX has been specifically designed to adapt itself to the heads of most mainsails. Thus it can be used in place of a 2:1 purchase on a mainsail halyard making it easier to tension the halyard and hoist the mainsail. Sold individually. Available in several sizes. Precision forged in France. Breaking Load is the static load at which total failure, by rupture or deformation, occurs. Safe Working Load is the maximum static load the product can endure without deforming. Prudence dictates not exceeding 80% of the functional limit. Widely recognized for their first-rate materials, design and workmanship, Wichard products are highly documented, ISO 9001 certified, and backed by a 5-year warranty. All Wichard hooks are hot forged and passivated, providing exceptional reliability, eliminating internal structural defects and protecting against oxidation. Wichard's HR, high resistance, 17.4 PH alloy is one of the strongest available in marine hardware. This slightly magnetic alloy is used in their top-end products. Because Wichard hooks are forged, when they are stressed to their limits they will show signs of deformation first and will never break suddenly. Only forging creates a superior steel product, by increasing its elasticity and maximizing the steel's internal strength. 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.
