Two-Piece Stainless Steel Duplex Sleeves

Upson-Walton's Two-Piece turnback Sleeves

Upson-Walton's 2 pc turnback sleeves by Muncy were designed and initially manufactured for the US Navy. Our product has many applications, as customers have used our sleeves in marine, logging, tie-down, and pulling applications, to name a few. Our sleeves have been tested by many customers to terminate ropes that are harder or impossible to splice into a flemish eye, like certain swaged ropes, compacted ropes, ropes with plastic impregnation, higher strand construction than 6 stand general purpose ropes, to name a few. Their testing allows the ropes to be rated for their end users. Some customers have elected to use 3 of our turnback sleeves based on their testing for their construction of rope and application!


Using 2 pc turnback sleeves

Our sleeves are swaged onto the rope when forming a turnback, or loop-back eye in a wire rope sling. When making the sling, our sleeves must be carefully spaced from each other and the dead end of the rope must properly protrude past the sleeve furthest from the eye at least 1 times the diameter of the rope. Our 304 stainless sleeves are specially made for the swaging application and then taking the load when the sling is in use. Our "Hour Glass" or "Figure 8" design inside the sleeve gives better fill factor and strength.
