Bulkhead Wrench


Easily and securely tighten cable penetrators in tight quarters with this specially designed wrench! It’s made of hardened tool steel for a long life and has a 1/4″ socket adapter to be used with a socket wrench.



The cable penetrators have wrench flats that making tightening relatively easy, but when you pack a bunch of them together it gets more difficult. That’s particularly true with the 18-hole end-cap used on the BlueROV2. This specially designed wrench makes it easy to tighten penetrators in tight spaces.

The wrench is made of hardened chrome-plated steel and includes a lever bar designed to apply just the right amount of torque to tighten the penetrator. This tool is a great addition to your field toolbox!

Note: We recommend tightening the penetrators with your fingers and then use this wrench to tighten them an additional ~1/16 of a turn. When done, you should not be able to remove the penetrators by hand.
