Tylaska Main Halyard Shackles

Tylaska Main Halyard Shackles

Tylaska's halyard shackles have the highest strength-to-weight ratio of any existing halyard shackle on the market. A captive 17-4PH stainless pin makes for trouble-free operation. The all-metal machined line thimble allows for use as a 2-1 purchase without the wear or melting that occurs with plastic molded thimbles. Lines can also be permanently spliced for a fixed halyard.

Tylaska CNC machines the 3D shackles from a solid block of aluminum. Type III hard coat anodizing protects against corrosion. Laser engraving identifies the product without sacrifice to strength or risk of corrosion. A new generation design of the H8 over our original H8 halyard shackles further improves corrosion resistance and provides more thimble bearing area for 2-1 applications. The cross pin is made from 17-4PH to resist wear and bending. The pin is made captive to prevent loss but still allows the full throat width of the clevis. The size was made to fit standard sail headboards without adding any unnecessary weight. Strength was optimized by computer and then verified by numerous "make and break" destructive tests.

Antal Twin Halyard Block

Antal Twin Halyard Block

Antal’s Twin Halyard Block is designed specifically for use with a 2:1 main halyard. The block features an extremely high working load in relationship to its size. The block is hardly larger, and weighs little more, than a standard main halyard shackle with comparable working load. The extremely small sheave includes a High Load Composite Fibre Bushing.

This lightweight block is machined from a solid piece of “High-resistance” 17-4-PH Stainless Steel, with a captive and self-locking pin. Three sizes are available for boats from approximately 40 to 65 ft.

Wichard Halyard Key Pin Shackle

Wichard Halyard Key Pin Shackle

Key pins offer many advantages. The pin can easily be opened by a single half turn, but remains captive within the body of the shackle, it cannot be lost. The bar allows the halyard line to remain attached to the shackle. The bar that keeps the halyard captive has a rolled pin that can be removed, allowing the shackle to be attached to existing splices.

Ronstan Standard D Shackles

Ronstan Standard D Shackles

Provides high load capacity and compact size in a standard dimensional formed shackle. Ronstan shackles are strong, reliable and economical. Several basic types are available in a range of sizes for all applications. Smaller size bodies are produced from formed stainless steel sheet, while larger size bodies are from turned bar, coined at the ends. Pin heads are in compact slotted or coined for finger adjustment and some pin heads are frilled for the fitting of a securing wire.

Ronstan Wide D Shackles

Ronstan Wide D Shackles

Ronstan shackles are manufactured from grade 304 stainless steel. They are strong, reliable, and economical. Similar to the standard D shackles, but have a wider internal width clearance for fitting to wider, irregular shaped or multiple objects. Although they do typically have a lower breaking load than traditional shackles, they come in handle when fitting to those places where a standard shackle will not work.

Ronstan Load ratings explained - UDL (Uniformly Distributed Load) = Breaking load ratings relate to a load applied across the full width of the shackle pin.  PL (Point Load) = Breaking load relates to a point load applied at the center or one side of the shackle pin.

Yale Loups

Yale Loups

Make it light. Yale Cordage has unveiled LOUPS - a new product designed to replace steel shackles, providing greater strength at a fraction of steel's weight. Using UHMW Braid, Yale's engineers overlap consecutive coils, then splice the ends to create a single loop of overlapping lines. That multiple-strand loop is then encased in a 48 carrier polyethylene sleeve to reduce abrasion. The completed loop then undergoes Yale's proprietary process to equalize stress across each strand, ensuring maximum strength when the finished LOUP is ultimately installed.

Yale tested their first LOUPS on Team Adventure during The Race, where they were used to replace steel hardware for a variety of applications. The 30 LOUPS that were used to replace Team Adventure's shackles resulted in a weight savings of more than 200 pounds. After The Race they did not look like they had been under stress and exposed to the elements for more than 30,000 miles. Yale has incorporated color-coded wear indicators in the sleeve's braid which also identify the LOUPS' strength rating. As they undergo use, the colored tracers will break down, indicating the need to replace the LOUP.
