B4 Sliding Anchors are used in conjunction with OWT and TWT ties to tie the inner and outer leaf to structural steelwork or concrete where a movement joint is required. They provide lateral restraint while allowing vertical movement. The B4 anchor is positioned within the cavity and fixed through two 7mm or 10mm holes to the underside of the structure and sliding ties are positioned to suit the wall coursing. A range of standard sizes are available but can be manufactured to suit customer requirements
The B4 Anchor is designed to service a maximum load of 1.5kN.
