Tension & Compression Systems

Specifying and Ordering

Ancon Tension Systems are supplied as full systems and are not available as individual components.

System lengths are measured between the centres of the pins in the forks. The maximum bar lengths available should be considered when determining the system length.

The Ancon Tension System can be specified as follows:

System/size/system length/material/finish

A fully polished Ancon 500 stainless steel system using 16mm diameter bar, 2750mm between the pins would be specified as:-

Ancon 500/16/2750/SS/6

The material and finish codes are from the following table.

Corrosion Resistance

Electrodeposited zinc coating Fe/Zn12/A to EN ISO 2081 on bars and discs will provide some protection against corrosion, but is only intended for systems that are internal installations. Hot-dip galvanizing to EN ISO 1461 will provide greater protection but should be considered as only part of the overall protection treatment. Stainless steel affords the greatest protection and does not require any further treatment.
