Aluminum End Cap with 18 Holes (4″ Series)

Regular price $78.00

This 18-hole aluminum end cap is compatible with the 4" Series Watertight Enclosure. It can be used with the BlueROV2 and adds four additional cable penetrations for more expandability!

This Endcap has a mixture of threaded and through-holes to allow more penetrations to be packed in. The outer eleven holes are threaded with standard M10 threads. The inner seven holes are through-holes just like our other end caps. All of the holes are compatible with all of our M10 penetrators.

One of the holes is spaced further from the others to allow it to be drilled and tapped for a 7/16″-20 thread, which enables the use of many typical subsea connectors in that hole. If you’d like to use this feature, you’ll have to drill and tap that hole yourself.
