4-1/8 in. (104 mm) Kydex Ring installs behind new or existing fire sprinkler escutcheons to cover oversized holes, including those made for fire assemblies where seismic design, earthquake bracing, or sway bracing are a factor. This 'beauty ring' is 1/32 in. (0.79 mm) thick, made from fire-resistant plastic, and has an interior diameter of 1-3/4 in. (45 mm).
An open hole around a fire sprinkler is both unsightly and, in rare cases, unsafe. This 4-1/8 in. (104 mm) Kydex Ring prevents particles from attics, roofs, or upper floors from falling into a sprinkler-protected room, eliminating the need to replace ceiling tile or drywall when mistakes are made.
