Rope accessories – rope shackles and rope shackles
In the Rope Accessories product group, you will find small parts needed for handling and connecting rope: eyelets (stainless steel or galvanized, in several sizes such as 10x65mm and 14x80mm) and rope shackles, which are available from brands such as Robline and Liros. The eyelet protects the rope loop from wear with a metal ring when the rope is attached to an anchor or other metal part, for example - without an eyelet, the rope rubs directly against the sharp edge of the attachment point and wears out quickly.
The choice of material for the hose should be made according to the intended use: stainless steel is best suited to seawater and does not leave rust stains on the rope or deck, while galvanized steel is a more economical option for less humid locations. The size of the hose should be adjusted to the thickness of the rope being used – a hose that is too small will not fit into the rope loop, while a hose that is too large will leave slack that reduces protection.
The rope shackle, on the other hand, enables quick and safe mooring without a knot – particularly practical, for example, in the connection between an anchor rope and chain or when mooring sails, where the connection must be able to be opened and closed quickly. Other mooring accessories, such as rope springs for equalizing the load on the bow bollard, can be found in other product groups in the Ropes, anchors and moorings section.
The correct sizing of the shackle and the rope shackle is more important than often thought: a shackle that is too small will not provide sufficient support for the rope loop, which can cause the rope to flatten and weaken over time, while a shackle that is too large will leave slack that exposes the rope to rubbing against the edges of the loop. The inside diameter of the shackle should match the thickness of the rope being used as closely as possible.
When choosing a material, stainless steel is recommended for long-term use in seawater, even though galvanized steel is cheaper at the time of purchase – rust adheres to the rope and can leave permanent stains, and a rusted shackle will lose its strength over time. It is worth testing the opening and closing mechanism of the rope shackle before use and lightly lubricating it so that it operates smoothly even after wear caused by salt water and sand. Check the shackle and shackle attachment points regularly during the season for wear and fatigue fractures, as these small parts often carry surprisingly high loads when mooring.
Keep a small supply of rope accessories on the boat, as a shackle or rope can be lost or damaged unexpectedly - without a spare part, you will have to use a temporary solution that is not as reliable as the real part.
