Scanstrut DS21A-S Vertical Cable Seal - Stainless Steel 
1-1/4″ Bronze NPS to NPT Flange Adapter
IBVF Flanged Adapters have been developed to address several common problems in the marine industry.

- Accept standard thru-hulls into the base and standard in-line valves on top
- Provide a safe and sturdy assembly when in-line valves are used as seacocks
- For OEMs, prevent valve damage during engine or generator installation – the valve can be installed later
- Simplifies future valve replacement
