Due to the special workings of the torque nut, the bar is allowed to rotate and the inner expander engages with and tightens onto the inner wall leaf. At the correct pre-designed torque the inbuilt resistance offered by the special torque nut is overcome, allowing the nut to rotate down the bar and tighten the outer expander to similarly engage with and tighten onto the outer wall leaf.

You will need the Setting Tool for Mechanical Ties here - Setting Tool for Mechanical Wall Ties and an 11mm drill bit of appropriate length. 

Fixing Instructions

1. Drill an 11mm hole to a minimum depth of 70mm into the inner leaf. Remove dust and debris,

2. Insert Neoprene Tie key into drill and fit over the torque nut. Run nut slowly down until resistance is met – the tie is now fixed. Do not over tighten. Ideally drills should the run at a slow speed and high torque setting for the most efficient fix.

3. To put ties in manually fix the manual key onto the special torque nut and turn clockwise until the tie is fitted. Initial resistance will be met then give way temporarily when the torque nut moves down the bar to engage the outer leaf. This is normal and resistance will again be met whilst the outer leaf is tightening
