When to Use PT250 Wall Ties

PT250 wall ties are typically used where the cavity width is between 100mm and 125mm and the specification calls for a Type 4 housing tie. They are a common choice for domestic masonry cavity walls and extensions where this cavity range and tie type are suitable.

If your cavity is 75–100mm, a 225mm wall tie may be required. If your cavity is 125–150mm, a 275mm wall tie may be more suitable. Always check the stated cavity range before ordering.

Important Selection Note

Wall ties should not be selected by length alone. Before ordering, check the required tie type, cavity width, wall construction, building height, exposure conditions and any engineer, architect, building control or warranty-provider requirements.
