The Ancon 500 is a high performance tension system. It is available in various sizes from 8–42 mm in both carbon and stainless steel. The Ancon 500 System, with its wide range of components can be used to create a variety of assemblies, from simple tie bars to complex bracing systems involving several bars joined at one point. Special anchor plates and discs can be manufactured to suit project requirements. Connecting plates are designed to suit particular applications. Ancon tension systems are supplied as full systems and are not available as individual components.

Ancon 500 Stainless Steel system is recommended for applications that demand corrosion resistance and a maintenance-free life, or where an attractive polished finish is required.


  • The system can be extended over the maximum bar length by the inclusion of couplers or anchor discs/ cross couplers.
  • The bar used in the system has a minimum yield of 500 N/mm².
  • Isolation supplied as standard with stainless steel systems.
  • The fork connectors and couplers are designed to allow adjustments to be made to the system length without the need for turnbuckles.
  • CE marked to BS EN 1090-1.

Standard product features


- Fork connectors and locking nuts:

  • Fork connectors are supplied with a locking nut. Forks and their locking nuts have left or right hand threads, and are supplied complete with a pin.
  • Each stainless steel fork is supplied with two clear, self-adhesive, PET (polyester) washers to isolate the system from a connecting plate of a dissimilar metal.

- Pins:

  • Two-part locking construction and once installed are flush with the fork.
  • Stainless steel pins are supplied with a PTFE coating around the barrel to isolate the system from a connecting plate of a dissimilar metal.

- Tie bars:

  • Tie bars have a right-hand thread at one end and a left-hand thread at the other.
  • Flats are pressed into the bar close to each end to allow the bar to be screwed into the fork connectors.
  • Carbon steel bars are available either untreated with the electrodeposited zinc coating Fe//Zn12//A to EN 12329 or are hot-dip galvanized to EN 1461.
  • Stainless steel bars are bright drawn as standard or hand polished when required.

- Couplers:

  • Couplers have right and left hand threads and are used in applications where more than one bar is required between forks.
  • Supplied with locking nuts for each end of the coupler.
  • Couplers are machined from bar and can have the provision for a hanger to be fitted to limit the deflection of bars of 16 mm diameter or greater.

- Anchor discs:

  • Allow up to eight bars to be connected together.
  • Can be used at the centre of conventional cross-bracing, or where several bars need to be connected at one point.
  • Machined from plate and can be supplied with a surface finish to match the system.

- Cross couplers:

  • Offers a streamlined alternative to an anchor disc when forming a cross brace.
  • Minimizes the number of fork connectors and locking nuts required.
  • Available in zinc-plated carbon and stainless steel to suit bar sizes 10–24 mm.
