Victaulic’s VicFlex Style AB6 Assembly for cold storage applications reduces hands-on installation time. In addition, the AB6 Bracket eliminates condensation. If condensation drips down the sprinkler barrel and freezes, it can interrupt the sprinkler’s spray patterns.The bracket also combats differential movement between ceilings. In the event of seismic activity or any settling of a building, the external structure and the freezer box inside the structure can move in different directions and the sprinkler will move with the activity and adjust accordingly.
