StiffClip® TD

The StiffClip® TD series’ unique design allows for the anchoring of wood or steel studs to the foundation incorporating a ¾” steel stiffening plate for strength. StiffClip TD resists vertical uplift loads for an effective solution in wall stud tie-downs or as the anchorage component in conventional, strap/gusset-plate shear wall construction.
Features
  • Guide holes for connections to stud and deck
  • Stiffening plate for additional strength
  • Clip utilizes certified, 55ksi steel
  • Reduces material (replaces heavy steel angles)
  • Extensively tested
