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. Each strain relief comes with locking nut.
