A single 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.
We also stock a twin tube tie version.

Load Capability:
The maximum load on the bracket is 10kN in any direction.
Load capability of this product is normally limited by the loads achieved by the fixings and/or base material but in any event should not exceed the 10kN specified above.
Horizontal Loads (bending moments):
When used horizontally, failure of the bracket is 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 is 850Nm or 2.83kN at the end of the tube (subject to pull out tests of 10kN being achieved)
When attached to Concrete with 12x100 CS bolts, the maximum load is 2210Nm or 7.36kN at the end of the tube (subject to pull out tests of 26kN being achieved).
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.
