Types of Wire Rope Sling Terminations
Standard 6-strand UNI-LOC® swaged Flemish Eye Sling.
UNI-LOC® swaged TRI-Flex® Flemish Eye 3-part Sling.
Flemish Eye Splice
The most popular splicing method. Its safety relies mainly on the craftsmanship of the correct splicing method. The sleeve’s function is to secure the strand ends around the rope body. Steel sleeves are very rugged and withstand a lot of abuse. The flemish eye splice is the preferred method in the construction industry and for most industrial sling applications.
The flemish eye splicing method can ONLY be used for 6-strand ropes and standard Tri-Flex® sling types.
Loop end terminations for rotation resistant- and non-rotating ropes, and for ropes having more than 6 strands, require either aluminum- or loop-back steel sleeves.
Flemish eye sleeves are also available in stainless steel to be used on stainless steel rope.
Note: Stainless steel slings which have sleeves made from regular carbon or aluminum metal may experience accelerated deterioration due to an electro-chemical reaction between the two metals. Particularly if the slings are used in saltwater or corrosive environments.

Aluminum Sleeve Loop Back Splice
This splice is fabricated by forming a loop eye and pressing an aluminum sleeve over both rope parts. The strength depends 100% upon the integrity of the pressed sleeve.
Unirope fabricates these splices according to the strict European standard EN 13411, using original specification sleeves and dies as specified in that standard.
This method is used for 8-, 9-, and 10 strand as well as non-rotating rope types (19×7, 19×19, 24×7, 34×7), and when Tri-Flex® and Gator-Flex® slings are requested with thimbles at the ends.

Steel Sleeve Loop Back Splice
Essentially the same method as aluminum loop back splices, but fabricated using steel sleeves slightly smaller in diameter. Available also in stainless steel, these sleeves are sometimes used on larger diameter stainless steel ropes. Special UNI-LOC® steel sleeves are used on Gator-Flex® slings.
The rope is “looped back” into a sleeve (steel or aluminum) which is swaged to form a permanent load bearing bond between the two rope parts.
The rope is inserted into the fitting bore and the fitting is then swaged onto the rope. This method is used for buttons, threaded studs, open and closed sockets, and to attach a load hook directly onto the rope. This method can be used with nearly all rope constructions and produces a high efficiency bond. Unirope manufactures a wide variety of custom made swaged fittings to meet your specific demands.

While some people may debate whether spelter socket terminations are true “sling” fittings, they are generally included in such catalogue sections. This type of end termination has traditionally been the method for determining the rope’s actual breaking strength. All other end terminations are being compared to the strength efficiency of spelter sockets which is considered 100% of the true actual rope strength.
