Flat Tension Bracing



Pre-punched galvanised steel tension brace designed to brace timber wall frames in domestic construction.

This pre-punched galvanised steel brace is:

  • Very useful in situations where bracing cannot be cut into studs.
  • The ideal tension bracing system when used in conjunction with a Multi-Tensioner.
  • Practical – it helps reduce on-site labour time as studs do not have to be notched.


Two individually cut pieces of Flat Tension Bracing are required to brace a timber framed wall section.  These pieces should overlap to form an ‘X’.

  1. Secure first end of one piece of bracing into position using 30mm x 2.8Ø Multinail nails.
  2. Stretch the Flat Tension Bracing over the entire panel to be braced, ensuring the brace is taut.
  3. Secure the second end while maintaining tension on the brace.
  4. Repeat this procedure for the second piece of Flat Tension Bracing, ensuring an ‘X’ is formed.
  5. Secure the Multi-Tensioner in each length of Flat Tension Bracing to remove any remaining slack.
  6. Fix T-Plate, Stud Tie or Nail On Stud Tie as required (refer to individual Multinail product brochures).

Please use the relevant Standards to determine the number, location and tie-down of bracing units.  Bracing capacities stated are relevant for wall heights up to (and including) 2.7m.  For wall heights greater then 2.7m, please refer to AS1684.
