Striker plates used for protection where flexible gas piping passes through structural members and is restricted from moving to avoid nails, screws and other potential puncture threats. Steel conduit is used to provide additional protection where striker plates cannot be easily installed. For attachment to the CSST gas piping system, a single bonding clamp must be attached to either a segment of steel pipe, a rigid pipe component or to the XR3 brass hex fitting. For attachment to a segment of steel pipe or a rigid pipe component any bonding clamp listed to UL467 may be used. For attachment to a XR3 hex fitting clamps manufactured by Erico (part number CWP1JSH for 3/8" & 1/2", CWP2JSH for 3/4" thru 1 1/4" and CWP3JSH for 1 1/2" & 2") must be used.
