Storm King Enterprises Product Lines

• HydroClaw 8-Inch Bracket: Steel zinc-oxide-coated bracket for 8-inch nominal diameter expansion tanks.
• HydroClaw 11-Inch Bracket: Steel zinc-oxide-coated bracket for 11-inch nominal diameter expansion tanks.

Why Contractors Specify Storm King Enterprises

The HydroClaw transfers expansion tank weight to structural framing rather than the threaded pipe connection, preventing thread fatigue and leaks over time. Compatible with most major expansion tank brands by body diameter. Steel zinc oxide construction resists corrosion in mechanical room environments.

How to Choose a Storm King Enterprises Product

Select HydroClaw size based on the expansion tank body outside diameter: 8-inch for smaller residential tanks, 11-inch for larger residential and light commercial tanks. Mount to structural framing before connecting the tank to system piping.
