Staifix HRT4 Type 4 wall ties are light duty housing ties, suitable for cavities from 50 to 150 mm and can be used for domestic housing up to 10 metres in height.

The Staifix HRT4 has a measured dynamic stiffness of <4.8 MN/ m³, at a cavity of 50–150 mm and is therefore suitable for internal separating (party) walls. The HRT4 can be used with all approved robust details for cavity masonry separating walls, both traditional and thin joint blockwork. The ties carry CE marking and can be used in line with NHBC standards.
