HEAD RESTRAINT RANGE
The TTIHR Head Restraint is designed to restrain the top of the inner leaf of cavity walls. The TTIHR 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 in to the horizontal mortar joint.
The TTIHR is available with 3 head options i.e., slotted, 10mm hole and 6mm hole. The standard TTIHR is supplied to suit a standard block but specials can be made to suit site requirements.
