The ULT Reinforced Angle Bracket provides a way to make a straight angle of 90° connection. These angles also have well-defined fastener locations, and testing ensures that the tabulated load values account for connection eccentricities. The ULT pre‑bent angle speeds up onsite installation.

Material

Carbon Steel 1.5mm thick

Finish

Z275 Galvanised

Features & Benefits
  • Removes the guesswork for making perfectly square connections
  • Reinforces 90-degree connections
  • Stronger than angled nailing or screw fastening
  • Staggered fastener pattern reduces the chances of timber splitting

  1. Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the Australian Capacity Factor, or the NZ Strength Reduction Factor (φ), and applicable the k modification factors following AS 1720.1 and NZS 3603 and (2) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation.
  2. For Australia, the Capacity Factor (φ) is 0.85 for nails and screws for structural joints in a Category 1 application. Reduce tabulated values where other Category applications govern. For NZ, 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 Australia Joint Group JD4 per AS 1720.1 Table H2.4 and New Zealand Joint Group J5 per NZS 3603 Table 4.1.
  5. Design capacities are for one cyclone tie.
  6. Design capacities in the F1 direction are not intended to replace diaphragm boundry members or resist cross-grain bending of the truss or rafter members.
  7. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces may be considered.8
  8. Cyclone ties installed on the outside of the wall assume a minimum 90mm overhang of the rafter/ truss member.

E5_Reinforced Angle Bracket

E5 Reinforced Angle Bracket is suitable for structural applications in framing and timber-frame houses for general connecting of timber at 90° angles. Typical applications include fixing trusses, studs, purlins, beams and posts.

The A21 and A23 Reinforced Angle Brackets provide a way to make a straight angle of 90° connection. The A21, A23 L shape angles are load rated, providing the correct thickness and number of fasteners.

A34

The versatile A34 and A35 Reinforced Angle Brackets provide a way to make a straight angle of 90° connection. The A35 Angle Bracket’s exclusive bending slot allows instant, accurate field bends for two and three-way ties.
