ULTIMA Anti-sway Wire System



 Ultima wire grips are widely used as anti-sway bars in equipment construction


Since its establishment, Ultima Wire Grips have been used in our products to meet the needs of the industry.

Ultima wire grips are characterized by their high gripping force while being gentle to the wire.


In fact, Ultima wire grips are used not only in the construction hardware industry, but also in the inspection equipment for wires used in industrial equipment and in the building equipment industry.


In particular, we have shipped more than 1 million units since 1990 to a certain electrical installation materials company in JAPAN as adjusting and fixing fixtures such as wire slide stoppers for equipment used to install lighting and air conditioning fixtures.*1

 What is the difference between Ultima grips and ordinary wire stopper fittings?


When wire grips are used to prevent equipment from swinging, common bearing-type grips are inadequate for the load.

In contrast, Ultima grips are strong enough to safely suspend heavy objects with smaller diameter wire.


Since 1990, we have shipped more than 1 million units of these grips to electrical installation material companies in Japan as adjustable fixtures to prevent wires from swinging when used in lighting and air-conditioning equipment.


Furthermore, as a feature of the grip, the length of the wire can be easily adjusted by operating the pin at the tip of the grip.


  Ultima grip :Shoe type grip Other grip :Bearing grip

Shoe type grips (surface fixation) distribute the load by clamping the wire between two surfaces, thereby reducing the load on the wire. The original strength of the wire is maintained.


The shoe-type grip is a proprietary technology of Ultima.

Bearing type grips (point fixation) have less braking force because the force is concentrated at a single point, and the wire is easily damaged. The wire is easily damaged. 

  • High strength and high safety ratio
  • Utilized in industrial products 

  • Often utilized in display and interior design
  • Surface contact
  • Strong grip, especially resistant to vibration *1


  • Point contact
  • Grip strength is low. Weak against shock and vibration *2


  • Grip force is strong.
  • Difficult to release by hand (finger) *3

  • Grip force is low
  • Easy to release by hand (finger)

Burden on wire

  • Surface fixation
  • Less burden due to distributed load
  • Less damage and indentation such as strand breakage and waviness


  • Point fixation
  • Load is concentrated, so there is a heavy burden.
  • Damage and indentation such as strand breakage and waviness are inevitable.
  • Wire maintenance is necessary
  • Original design, not an off-the-shelf product
  • Other companies cannot easily manufacture (difficult to manufacture equivalent products)


  • Uses off-the-shelf bearings
  • Easy to manufacture

*1:90% to 100% of JIS standard wire breaking load of 170kg based on SUS304φ1.5mm (7×7) wire test values.

*2:50-70% of 170kg of JIS standard wire breaking load based on SUS304φ1.5mm (7×7) wire test value.

*3:Hybrid mechanism (pat.p) is also available to solve the disadvantage of difficulty in releasing the gripping force.


 Basic Grip Operation



 Grip Strength


Wire Maximum Static Load Value Allowable Load Value


1670N~1880N (170kg~192kg)

540N (55kg or less)


5,390N (500kg) 1,670N (170kg or less)

* The maximum static load value is the maximum value when a stainless wire (7 x 7) is used for the grip in a stationary state and pulled until the wire breaks (when it breaks).

* The allowable load is calculated with a safety factor of approximately 1/3 of the maximum static load value, but the safety factor should be considered depending on the conditions of use.

* The maximum static load value varies depending on the type of wire used. Please contact us if you have any questions.

 Features of ULTIMA Anti-sway Wire System


  • One-touch locking and adjusting function
  • Lock by simply inserting the wire. Unlock by operating the pin.

  • Easy operation ensures uniform work efficiency during installation and repair.

  • High strength
  • The maximum static load of the grip is almost equal to the JIS standard for wires. It can be used within a sufficient safety factor.
  • Wire-friendly
    • The internal locking mechanism reduces damage to the wire, making it safer, especially when subjected to impact.
  • Open design concept
    • Standard dimensions allow the use of commercially available nuts and anchors.
  • Compact design
    • The uniquely compact body expands the range of applications.


  • Please use wire cutters for wire cutting to avoid fraying of strands.
  • The grips have a strong locking force, so it may take more force to unlock the grips after a load is applied.
  • The torque value of grips is lower than that of normal bolts because of the mechanism inside. Do not over-tighten the grips (the threads may be damaged).
  • If the cut end of the wire is untwisted, it will be difficult to insert the wire into the grip. Cut the wire cleanly and twist it to insert it smoothly.
  • Cut the excess wire that comes out of the grip, leaving 40 to 50 mm of excess wire. Please note that if the excess wire is forced and bent, it may affect the locking function.
  • Do not use wires other than those specified by us. Also, for safety reasons, do not use damaged or bent wires.
  • Do not allow the wire to come in direct contact with the edges as it may be cut or fall.
  • The mounting position of the anti-sway bar should be firmly fixed near the supporting member.
  • Do not use the product outdoors or in locations subject to high temperature, high humidity, shock or vibration.
  • Do not apply paint or oil to the grips and wires.
