Metal cap to suit male 4 pin connector.
This is a single cap with chain retainer to be used on a standard 4 pin male connector that is left exposed and screws on to seal this from dirt and water.
Mainly used where 4 pin cables are disconnected and require protection from the elements, the cap screws onto the male end.
If male and female capping is required, use the CH-4FMBLANK which has both male and female parts in plastic.
