Stone Support
ACS stone support cleats carry the dead load of natural stone façades and panels back to the structure, tailored to each project’s stone size, density and cavity width. The SA and SB ranges suit cavities from 10mm upwards and use the Alpha II system for vertical adjustment on site. Involve our technical team early, alongside your stone supplier, to get the right cleat and fixing positions from the start.
SA Range: For Small Cavities 10mm And Above
The SA range is designed for small cavities of 10mm and above, using an Alpha II pad and washer for vertical adjustment. SA1 uses a standard leg with welded dowels and is available in continuous lengths. SA3 uses an overbent leg, while SA4 is a flat plate for use where lower restraint is taken by separate stone ties. Both cover the same small cavity range and are supplied in lengths up to a maximum of 200mm.
SB Range: For Larger Cavities (Greater Than 50mm)
The SB range is designed for cavities greater than 50mm, incorporating the ACS Alpha II Bracket and Washer to suit the larger cavity. SB1 uses a standard leg with welded dowels and is available in continuous lengths. SB3 uses an overbent leg, while SB4 is a flat plate for use where lower restraint is taken by separate stone ties. Both cover the same larger cavity range and are supplied in lengths up to a maximum of 200mm.
