A twin tube tie bracket used for the construction of hand rails and/ or similar tube assemblies. Comprises of an extra thick, extra-long, back plate drilled with twin 14.5 mm holes and a single tube 300mm long welded to its face. Designed with hole centre’s of 150mm to spread the load over three courses of brickwork or to align with mortar joints. Comes complete with hi vis yellow end cap.

Normally used for concrete and masonry connections in conjunction with 12mm Excalibur bolts. Can also be fixed with conventional nylon plug & coach screw.

Tensile Load Capability:
The tensile load capability of this product is limited by the pull out load of the top fixing, caused by the rotational force of the tube being forced downwards about the heel of the bracket.
When attached to brickwork with 12x100 CS bolts, the maximum load if 850Nm or 3.4kN at the end of the 300mm tube (subject to pull out tests of 12kN being achieved).
When attached to concrete with 12x100 CS bolts, the maximum load if 2210Nm or 47.36kN at the end of the 300mm tube (subject to pull out tests of 26kN being achieved).

Shear Load Capability:
The maximum allowable shear load of this product is 25kN calculated after a safety factor 1.6 is applied to the weld tests. This may not be the actual load that can be applied as the working shear load may be reduced by the capacity of the fixings and/or the base material.

Quality Assurance
The brackets are batch tested and MPI inspected for ultimate performance. The weld strength has been tested in excess of 40kN. All technical data and calculations are available upon request.

Please take note of installation details:

  • Performance of the bracket is 100% dependent on the load applied to the top fixing.
  • If the load is insufficient, it cannot be transferred through the bracket to the scaffold.
  • The installer is legally obliged to perform preliminary tests to calculate allowable loads.
  • They also require a design or compliance sheet.

 

Also known as a "cast-off" or "t-off" bracket.
