Ancon Tension Systems consist of a range of components.
Fork Connectors and Locking Nuts
Ancon fork connectors are supplied with a locking nut that provides a neat transition from bar to fork and ensures the connection is secure. The internally threaded section of the locking nut is recessed to allow the threaded end of the bar to be hidden when the installation is complete.
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.
The pins are a two-part construction and once installed are flush with the fork. The installation requires a twin-pin driver. This type of fixing, known as ‘Snake Eyes*’, allows a high torque to be achieved without damage to the pin.
Stainless steel pins are supplied with a PTFE coating around the barrel to isolate the system from a connecting plate of a dissimilar metal.

Anchor discs allow up to eight bars to be connected together. They can be used at the centre of conventional cross bracing, or where several bars need to be connected at one point.
Ancon can design and manufacture plates in special shapes to replace standard anchor discs and suit the aesthetic requirements of an application.
When forming a cross brace, a Cross Coupler offers a streamlined alternative to an anchor disc and minimises the number of fork connectors and locking nuts required. Cross Couplers are available in zinc-plated carbon and stainless steel to suit bar sizes from 10 to 24.
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. These allow the bar to be screwed into the fork connectors and adjustments to be made at any time after assembly. The availability of each size of bar is given below. All bars are cut to a tolerance of ±2mm of the specified length. Maximum bar lengths below are in metres.
Maximum Available Bar Lengths - Ancon 500 system
HDG = Hot-Dip Galvanised
Maximum Available Bar Lengths - Ancon 360 system
HDG = Hot-Dip Galvanised
Note: Material in excess of these lengths can be sourced to meet special project requirements. Contact Ancon for more information.
Couplers have right and left hand threads and are used in applications where more than one bar is required between forks. They can be fitted with a hanger to limit the deflection of bars of 16mm diameter or above.
Ancon is exhibiting at the 2016 NZ Bridges Summit on 1st - 2nd November in Auckland. The conference is endorsed by the NZ Transport Agency (NZTA) and we will be showcasing our BT range of threaded reinforcement couplers, our MBT range of bolted couplers and various Lifting Systems including our brand new EdjPro Narrow Anchor system.
Having recently identified issues with the performance of some batches of reinforcing steel supplied to us, we have introduced batch testing for all reinforcement used in combination with our BT coupler system in New Zealand to ensure compatibility.
