Simpson Stainless Steel Helical Thin Joint Masonry Tie 305 mm (1 Unit) (HELI07305A2)
Type 3 stainless steel cavity wall tie for thin joint blockwork systems of masonry construction and other applications where the joints of the inner and outer leafs of AAC masonry do not course.
Ties can be fixed directly into the AAC concrete block without the need for pre-drilling. A continuous helix ensures multiple drip points that prevent moisture crossing the cavity. Suitable for use with cavities from 50mm to 150mm.
Thin joint wall ties are cold-roll profiled and twisted to form a 7mm diameter helical tie with a cross sectional area of just 9mm2.
Can be used in conjunction with the IRC insulation retaining clip where insulation has to be retained in the cavity. An installation tool is required to hammer the tie into the AAC block, or alternatively use the SDS drill installation tool.
