The SB4 support cleat’s design allows it to carry stonework over cavities greater than 50mm. It incorporates an over bent leg. Also the SB4 benefits from the ACS Alpha II bracket and washer offering greater load capacity and increased adjustment.
The system shown is indicative and may vary in length depending on the design requirements.
However, the SB4 support cleat is only available in lengths up to a maximum of 200mm long.
