The Ancon ST1 wall tie is now available in five lengths to suit cavaties from 50mm to 150mm.
In its longest length, 300mm, the ST1 is ideal for cavities of 150mm. This tie allows for additional embedment in the inner leaf to help keep the tie horizontal during build, which can be difficult to achieve with a 275mm tie installed at standard embedment.
As a Type 1 Heavy Duty Tie to BS5628-1 (2005), a British Standard which classifies ties according to their strength and function, the ST1 can be used with any building in the British isles.
