Bloc-Lock Termalite Fixings

Insofast Bloc-lock cuts a spiral path 85mm into the wall as the tie is driven by a series of axial impacts.
Engineered with superior precise helical pitch technology to interlock perfectly and maximise performance. No drilling, excellent holding power and rapid installation rates. Corrosion resistant stainless steel.
Insofast Bloc-lock are suitable for use with insulated concrete formwork technology (ICF) if wall is pre-drilled with a 5mm pilot bore and driven to 55mm.
Insofast Bloc-lock masonry ties are available in packs of 50. For fixing Insofast Bloc-lock to Aircrete masonry (Celcon, Thermalite, Topblock, etc.) you need a Bloc-lock SDS Drive Tool.
Wall tie lengths indicated below are for thin joint Aircrete masonry. For tying to ICF walls, use 1 length shorter to compensate for reduced tie embedment depth.
