Steel fastening system SDB/SDV/SPB/SPV

for facade cladding

Frame cramps can be fixed to concrete, steelwork or masonry and have a single 7mm diameter hole (SDB) or an 8mm x 30mm vertical slot (SDV). Ancon M6 single expansion bolts are recommended for fixing to concrete and M6 set screws or SDTSS-38-5PT self-drilling screws for fixing to steelwork. Frame cramps can be fixed to masonry with suitable plugs and screws or resin anchors. SDB and SDV meet the requirements of Part E (Resistance to the passage of sound) for use in external cavity walls.
