The correct attachment of the end of the rope is highly important for the longevity and security of the guying. It must be ensured that the rope can not be frayed by movement and wear on sharp edges. In most cases the rope is held in a thimble and fixed by one or multiple screw clamps, most ideally with a double clamp. In addition to that the very end of the rope should be protected against fraying (fan out) by using another clamp or a cable tie or adhesive tape. The thimble can then be hooked up to a chain link or a carabine. When the attachment point itself is smooth and has no risk of fraying the rope then the rope can be attached directly to the lug without using a thimble. But please note that the breaking load of a rope is drastically reduced when tying a knot, depending on the knot by up to 30 or even 50%! So the use of a thimble is helping under thsi aspec tas well. Although the breaking load is reduced also when using a thimble, it is not reduced as much as when using a knot.
The mounting hardware by Mastrant is in most cases made of stainless steel type A4, i.e. a steel type which is also resistant against acid and seawater. This is not only beneficial on board a ship, but also on land, for example close to the sea. But even anywhere else exhaust fumes from chimney can lead to acidic precipitation which can harm metals. Please select the size of the mounting hardware in accordance to the rope thickness.
