Abstract: An adjustable socket for receiving a ferrule rope comprises an elongated body, a primary stop, a channel and an adjustable stop. The primary stop comprises an opening in the body dimensioned larger than a diameter of a rope portion of the ferrule rope and smaller than a ferrule end of the ferrule rope, and a surface of the body adjacent the opening against which the ferrule end can bear. The channel is defined in communication with the opening and extending along the body. The channel has a cross sectional open area larger than the opening and is dimensioned to receive the ferrule end of the ferrule rope. The adjustable stop is selectively actuatable to define a secondary stop spaced from the primary stop along the channel and against which the ferrule end can bear, thereby changing a length of the ferrule rope.
