Watertight-Single Hole Strain Relief

Watertight-Single Hole Strain Relief

1/2" NPT strain relief fitting for 1/2" knockouts to pass wire into combiner, disconnect, or breaker boxes.  One fitting accommodates two standard 10 gauge wires, often a positive and negative from a single string of panels.  A twist-cap compresses the internal rubber grommet for a snug weather tight fit.  Some customers will take the extra step of applying a small silicon bead at the end of the installation, for a greater degree of protection in cases of extreme exposure.
