Helical strap ties are long-series 12mm CD ties that act as tension straps to connect the facade of a building to a wall that runs perpendicular to it. Installation of this lateral restraint system is at least ten times quicker to drill and fix compared with cement-grouted tying techniques. The tension tie is ideal for pinning masonry arches, quoins and thick rubble-filled walls and meets the requirements of EN 845-1 and conditions for UKCA and CE marking.
