• 275mm and 250mm long have a diameter of 2.8mm 
• 225mm long have a diameter of 2.3mm 

 

The Light Duty Housing Tie has a multidrip feature preventing moisture from travelling across the cavity. The design of the tie means that it can be installed either way up. This product is tested as Type 4 (strength) and Type A (sound) to BS EN 845-1. For more information about this product please see the data sheet located below the image or contact us for advise from our specialist team!

 

Here is a table to show which length of wall tie suits which cavity width size:

 

Length of Wall Tie	Cavity Width
275mm	150mm
250mm	125mm
225mm	100mm

 

 

 

Additional Information:

With its combination of impressive strength, anti-corrosive properties and intelligent design, the Light Duty Wall Tie from BS Fixings is a truly remarkable piece of technology. Only after extensive testing has the product been made available; discover some of the results below...

The Light Duty Wall Tie is available in a choice of three standard sizes, each of which was subjected to extensive, robust and rigorous testing at Ceram Building Technology to ensure their fitness for purpose. 275mm, 250mm and 225mm stainless steel wall ties were tested in compression and tension over cavity widths of 150mm, 125mm and 100mm respectively, with all testing carried out in accordance with BS EN 846-6 Methods of Test for Ancillary Components for Masonry, Part 5 (Determination of tensile and compressive
load capacity and load displacement characteristics of wall ties).

The maximum declared values at ultimate load (expressed in newtons) for each tie are as follows:

• 275mm Tie: Tension 1220, Compression 514
• 250mm Tie: Tension 1879, Compression 638
• 225mm Tie: Tension 1256, Compression 557

The tests also showed that the Light Duty Housing Tie has a measured dynamic stiffness of 2.77MN/m3 in a 75mm cavity, making it far more than suitable for party walls at a standard density of 2.5 per square metre (the dynamic stiffness in a comparable 100mm cavity will be similar or even less.)
