RediFrame is designed to sleeve the wall, becoming an integral part of the wall system. In comparative impact testing, 18-gauge RediFrame withstood 850 impacts, this is over 500 more than drywall hollow metal. The difference is the Dunbarton anchoring system. Not only does RediFrame sleeve the wall, but it anchors to the wall using at least 30 fasteners through the face of the frame opening. Hollow metal anchors to the wall from the frame throat using only 6 to 8 anchors per opening that hold the frame away from the inherent strength of the wall.
