Expansion Plate

Viking is a proud world leader in the design and manufacturing of life-saving fire sprinklers. The Expansion Plate is just one of the industry-leading sprinkler accessories available to customers!   

In earthquake-prone areas, there are many system requirements that a sprinkler contractor must consider. And, there are often many solutions to various seismic requirements, such as the use of flex drops, swing joints, earthquake bracing, etc. One solution used in certain scenarios is to leave a one-inch annular space (i.e. a larger hole) around the sprinkler to allow it to move in an earthquake. Viking's expansion plate enables a clean, professional installation when this strategy is used.

Expansion plates have a 5" (127 mm) or 5-5/16" (135 mm) outside diameter and are available in either polished chrome or white. Custom finishes are also available upon request.
