Frame cramps can be fixed to concrete, steelwork or masonry and have a single 7 mm diameter hole or an 8 mm x 30 mm vertical slot. Ancon M6 Single Expansion bolts are recommended for fixing to concrete, set screws or self-drilling screws for steelwork, and suitable plugs and screws for fixing to masonry.Frame cramps should have a minimum embedment of 50 mm in the outer leaf. Taking site tolerances into account, Ancon suggests tie lengths which achieve a greater embedment.
