Product Description

The STI SpecSeal® Quick Clip™ Perimeter Fire Barrier System is an innovative curtain wall perimeter fire containment solution designed to speed installation
and improve worker safety.
Using pre-engineered U- and Z-Brackets, the system supports mineral wool and SpecSeal® coatings without the need for cutting or impaling pins. The Quick Clip™ fasteners lock insulation panels in place, reducing
installation time and minimizing sharp-metal hazards.
