Aluminum Swage sleeves are economical fasteners for loops or lap splices. An Ideal fastener for Galvanized Steel Cable.
Not recommended for stainless cable due to electrolysis.
Oval shaped sleeves allow for easier threading of cable.
All our aluminum ferrules are made of seamless aluminum and strictly follow the material composition and mechanical property requirements of EN 13411-3 (DIN 3093) standard.
Random samples have been passing 75,000 cycles in fatigue tests.

Foreword: Eye-splices with swaged sleeves are a secure method of terminating wire rope. Nicopress is often asked about the
proper press sequence when pressing oval sleeves. Other related questions are proper wire rope end protrusion “tail,” and,
clearance between the pressed sleeve and thimble. These are important questions which we answer below.
The most important sequences to avoid are ones which press an area on the sleeve in-between two previous presses as illustrated.
Reason: once 2 outer presses are formed followed by pressing an interior position, the middle press will cause sleeve
material to push (or flow) against the previously pressed outer positions possibly breaking wires and/or compromising the grip
strength of the 2 outer presses. All sequences below illustrate a 3rd press located between the 1st and 2nd presses:
When making an eye-splice, extend the wire rope cut-end a sufficient distance out of the sleeve so when pressing has completed,
some portion of the cut end (or “tail”) remains outside the sleeve. Reason: the material flows and lengthens the sleeve as it is
pressed and may cause the wire rope end to retract inside the sleeve. If the wire has retracted, the gripping strength cannot be
predicted since less rope is gripped by the sleeve, which may reduce the gripping strength between the wire rope and sleeve.
When using a thimble, position the sleeve from the thimble a distance of at least ½ of the wire rope diameter. Reason: when
swagging, material flow tends to lengthen the sleeve which may cause the sleeve to contact the thimble – possibly damaging the
wire rope wires and/or compromising the grip strength of the sleeve. Note: Proper press sequences are also shown for the 3-press
sleeve illustrated below.
It is imperative that you use the correct gauge that is supplied with the swagger. All Vanguard’s swaggers include a Go/No Go gauge so you can measure the swage correctly.
Sleeve Gauge will measure all oval or stop sleeves used on 1/32″, 3/64″, 1/16″, 3/32″, 1/8″, 5/32″, and 3/16″ cable.
When proper slot in gauge slips over the compressed area of the sleeve after swaging then swage is satisfactory.
Note: Each test gauge must be appropriate to the tool that was used in the swaging of the termination sleeve. Tools can produce crimps with a unique profile that may, or may not, exactly match the profile of terminations made with other tools having the same groove number.
Please make sure you are using the correct gauge that is paired with the tool profile.
