The ACS range of sliding anchor systems is designed for where the inner and outer leaf of masonry need to be tied back to the structure, whilst allowing diff erential movement. They are available in a wide range of lengths and fixing styles to suit the individual requirements of the building. The head of the anchor fixes to the soffi t or face of structure i.e. concrete slab or steel beam. The stem head dimensions and hole positions can also be altered to suit the customer’s specific requirements. This image illustrates a B4 head restraint fi xed to the underside of a concrete slab.
