The WBT Wall Brace Tensioner is an easy‑to‑use wall strap‑brace tensioner that takes the slack out of strap bracing, saving time over other methods. With the ability to pull as much as 20mm of slack out of a single strap, the WBT can play an important role in reducing deflection in braced wall panels. It resists tension loads only and should be used in pairs (one for each strap when in X‑brace configuration).

  1. Design Capacity is the minimum of the steel strap design tensile capacity calculated in accordance with AS/ NZS 4600 and the structural joint design capacity using the applicable the k modification factors following NZS 3603.
  2. The Strength Reduction Factor φ) is 0.80 for nails in lateral loading.
  3. Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased.
  4. Timber species for joint design is seasoned Radiata Pine, which is New Zealand Joint Group J5 per NZS 3603 Table 4.1.
  5. Use half of the required nails in each member being connected to achieve the listed loads.
  6. Calculate the connector value for a reduced number of nails as follows: Design capacities = (No. of nails used)/ (No. of nails in table) X table load
  7. Tension loads apply for uplift when installed vertically.
