Lateral Restraint Tie Kit For Joist Ends
 
This system is suitable for lateral restraint applications such as restraining bowing or bulging brickwork. For this system to work the timber joists must span onto the bulging / bowing masonry wall in question; ie and a fixing into joist ends is required.
 
This product is not suitable when the joists span parallel to the wall- for a suitable system click here for details for our threaded bar lateral restraint system.
