The thimble is placed in the loop made of rope at its end. It protects the rope from abrasion and, in the case of stiff ropes, also from excessive crushing by giving this loop the desired shape. It is suitable for both metal and plastic or plant ropes. The thimble has a groove along its entire length, into which the rope enters about 2/3 of its diameter. The rope can surround the thimble and be tightened, upon return, to the rest of the rope, or the thimble can be woven into the rope. Putting on and taking off the thimbles is extremely easy and fast.
