a wide cavity range.

The latest product part of Cullen's wall tie range (FT), the FT-125-150, is designed to restrain the external brickwork or blockwork back to the timber gable panels at roof level.

The wall tie provides a smart and secure solution for wider cavity wall tie applications in traditional brick and block builds. By allowing the use of factory-manufactured gable panels, the FT-125-150 not only reduces the risks associated with working at height but also helps accelerate the overall build process.
