R ® RASCOFLEXT"' Sprinkler Connections
eIia e cULus Listed, FM Approved
EDProduct Description
RASCOFLEXTm Sprinkler Connections are intended to connect AUG 10 2)ZZ
a branch line to a sprinkler using a flexible stainless steel hose
assembly. RASCOFLEXTM Sprinkler Connections are suitable CTY OF TI ARD
for use in suspended and hard ceiling applications such as BUILDING DI ISION
T-Bar ceiling grids, wood, metal stud, or hat furring channel
hard lid ceilings. Every package contains one (1)fully assem-
bled stainless steel flexible sprinkler system complete with
hose, branch line connection, and sprinkler connection, as well
as the pre-assembled bracket assembly to attach to the ceiling.
RASCOFLEXTM Sprinkler Connections are designed for use in 4.,
hydraulically calculated wet, preaction, or dry sprinkler sys-
tems per NFPA 13, 13R, 13D, and FM Global Loss Prevention
Data Sheets.
