This is what the bridge mount looks like before reattaching the long strut channel with the new depth sensor node.

Line up and place the U-brackets, still attached to the long strut channel, onto the bridge mount.

Once again, hold the node securely to ensure it does not fall while the U-brackets are being attached to the bridge mount.

This step will use the same 3/4" nuts and washers from the first step.

Using a 3/4" adjustable or socket wrench, secure the long strut channel and U-brackets to the bridge with the 3/4" nuts and washers. Tighten and secure.
