Frame cramps can be fixed to concrete, steelwork or masonry and have two outer 6 mm diameter holes and one central 7 mm diameter hole or an 8 x 30 mm fixing slot. Wincro WBEB M6 Expansion bolts are recommended for fixing to concrete, WBXS set screws or WBSD self-drill self-tapping screws for steelwork, and suitable plugs and screws for fixing to masonry. Large washers must be used with all WTS2E, WTS3E and similar ties with a slot. Frame cramps should have a minimum embedment of 50 mm in the outer leaf. Taking site tolerances into account, Wincro suggests tie lengths that achieve a greater embedment of 62.5–75 mm.
