Description



The TTIHR Head Restraint allows vertical movement between the inner leaf and the structure by using a rectangular sleeve which sits in the vertical joint and a top section bolted to the soffit designed to slide within the sleeve. A welded flange at the bottom assists with embedment into the horizontal mortar joint. The TTIHR is available with three head options:-

Slotted, 10 mm hole and 6 mm hole. The standard TTIHR is supplied to suit a standard block but specials can be made to suit site requirements.


The TTFHR Head Restraint is a flexible head restraint consisting of two angles fixed using a single M8 bolt, which effectively clamp the top of the wall. The fixing can be supplied to suit the full range of block thicknesses and are capable of restraining a 0.75 kN load.
