Product Overview

Type 4 Wall Ties 200mm for use in masonry cavity walls with a cavity width of 50–75mm, providing secure restraint between masonry leaves while allowing for differential movement.


As a Type 4 tie to BS EN 845-1, these are suitable for dwellings up to 10m high in sheltered environments, typically where basic wind speed is below 27m/s. Their classification ensures they are correctly specified for residential construction in low-exposure conditions.


Each tie features an indented profile to improve mortar bond and provide effective wall stability. At 200mm, they are specifically proportioned for cavities of 50–75mm, ensuring correct embedment into both leaves of the wall.

Manufactured from stainless steel, they are resistant to corrosion and offer long service life without need for replacement.
