Stainless Steel J-Lock Shackle by Tylaska > 8mm, 10mm, 12mm, 14mm, or 16mm Line Sizes > 17.4 PH High Strength S.S.

- Unlike many other manufacturers, Tylaska pursues a different product mission. Instead of looking for ways to cut corners and skimp on quality, Tylaska shackles are aimed to be the best possible product made based upon physics and not economics.

Model #'s J8, J12, or J20.

Many extra and exotic processes are used differentiating the Tylaska shackle from the normal piece of hardware.

First, every structural part is run through a procedure called hipping (high isostatic pressurization), which is a process normally only reserved for spacecraft and critical aerospace parts. This consists of heating the component to near melting point in a vessel containing inert gas. The gas is then pressurized and the softened component is squeezed and compressed to seal and collapse any underlying void or imperfection.

The result is a very dense and uniform material similar to a wrought or forged component, but in a shape or configuration impossible with forging. Next, heat treating is done in vacuum furnace to eliminate any chance of contamination.

Several testing processes are implemented such as zyglo and magnifluxs to identify any microscopic surface flaws or cracks that could go unseen by the unaided eye.

Each component is then run through a salt corrosion test to identify any contamination or chance for staining and ultrasonically cleaned afterwards.

Finally, each and every snap shackle is tension pulled to 50% of its breaking strength and also released under load.

This is not a random statistical process, every single snap shackle is pull tested and verified as to holding the stated working load.

After proof testing, the shackle is hand buffed and then cleaned again.

Finally, one last thorough hand inspection is done on each item to verify that nothing is left unchecked.

The result is a shackle that could pass as a piece of jewelry and exceeded the specifications for a part used in the space shuttle.

Tylaska shackles are not the least expensive, but they are quite possibly the best.

Some people may call it overkill but Tylaska calls it security and peace of mind for applications where failure is not an option.

The new low-profile Tylaska J-Lock shackle easily splices onto Genoa sheets, outhauls and halyards, and fits through most Genoa blocks for fast sheet changes.

A unique patented double-locking plunger locks in two directions for the ultimate in flog-free operation.

Available in several sizes.

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.
