For Flemish eye wire rope splicing.
• Designed for low temperature toughness.
• Resists cracking when swaged (equals or exceeds stainless steel sleeves).
• Special processed low carbon steel.
• “COLD TUFF”® for better swageability.
• Sizes 6 - 7 through 37-38mm satisfy the type testing requirements for flemish ferulle secured systems per EN 13411-3:
2004, except those additional requirements defined for crane hoist rope.
• Can be stamped for identification after swaging without concern for fractures when following these directions.
• Use round corner stamps to a maximum depth of 1.38. The area for stamping should be on the side of the sleeve in the plane of the sling eye, and no less than 7mm from either end of the sleeve.
• Standard Steel Sleeve terminations have efficiency ratings as follows based on the catalog strength of wire rope.

• Swage Button terminations have an efficiency rating of 98% based on the catalog strength of wire rope.
• Special processed, low carbon steel.
• COLD TUFF® for better swageability.
• Stamp for identification after swaging without concern for fractures (as per directions in National Swaging Brochure).
NOTE: S-409 Buttons are recommended for use with 6 x 19 or 6 x 37, IPS or XIP (EIP), RRL, FC or IWRC wire rope.
Before using any National Swage fitting with any other type lay, construction or grade of wire rope, it is recommended that the termination
be destructive tested and documented to prove the adequacy of the assembly to be manufactured.


• For turnback wire rope splicing.
• Special processed low carbon steel.
• Turnback terminations have efficiency ratings of 94% based on the catalog strength of wire rope.
• Designed for lower temperature toughness.
• Resists cracking when swaged (equals or exceeds stainless steel sleeves).
• COLD TUFF® for better swageability.
• Stamp for identification after swaging without concern for fractures (as per directions in National
Swaging Brochure).
NOTE: S-506 Duplex sleeves are recommended for use with 6 x 19 or 6 x 37, IPS or XIP (EIP), RRL, FC or IWRC wire rope.
Before using any National Swage fitting with any other type lay, construction or grade of wire rope, it is recommended that the termination be destructive tested and documented to prove the adequacy of the assembly to be manufactured.
